@Bilun, who's thoughtful response I appreciate greatly....
Trying to quote each individual part of what you said is going to be difficult given the nature of the device I am responding to you with, so I'm going to number my responses...the numbers will loosely correspond to "segments" of your post:
1. The corvettes were microed somewhat, not nearly as much as flak...illuminators can essentially fire in all directions (side beams can shoot behind pretty well), so no matter where you put the corvettes, they are going to get shot at, there's really no "blind spot" you can hide them in......I suppose you could order the corvettes to hold position so that they wouldn't get hit by all the beams, but then your corvettes wouldn't be using their rear weapons and maybe not even all side weapons...
2. Illuminators do have disadvantages, and I'm not unwilling to acknowledge those...in the early game, I don't find the focus firing to be as much of a problem, because players are less likely to use double cap starts and corvettes incline caps to retreat sooner than in diplomacy...I won't say it's irrelevant, but the lack of FFing is not something I find too problematic in the early game, I would rather have ships that perform better against fleets (which Illuminators do)...the only early game situation where I really hate having only illuminators is if Vasari SB your HW early game (then I'm very glad to have kanraks or LRMs)...
3. In my experience, 3 military labs is no longer as much of a problem as it was in diplomacy, mainly because of moons now spawning next to the HW...I really don't find it that hard to get illuminators out early unless you didn't have both a moon and asteroid connected to your HW...recently I have tried to make early game fleets relying heavily on illuminators, and so far it has worked better than I would have expected...that is why I began this investigation, because intuitively I would have thought I'd be much better with disciple+corvette rushing...so far I have found illuminators to be great early game...you don't necessarily skip the disciple+corvette phase, but I've tried to get illuminators in as early as possible and so far it has worked, and I think a big reason is the build times...when under pressure, you simply can fleet faster with illuminators than if you went with other Advent builds...
4. The early TEC economy is honestly not that much better than Advent...if you are a frontliner, you probably aren't getting trade early on so the earlier trade isn't much of an advantage...all the economic techs that help TEC, such as development mandate, the trade techs, pervasive economy, etc. come much later in the game...the only true early economic advantage I find for TEC in the early game is the akkan's colonize ability...the terran pop techs also is a slight advantage over Advent (who need desert pop tech as prereq) but that's about it early game...if anything, Advent have an advantage over TEC because they get culture at tier 2....it's really only the eco players that get to benefit early on from TEC economic advantages....
5. In the early game, I think cost and construction times are more relevant than fleet supply...whether you have 1 fleet upgrade or 2, the upkeep is still low and if you are winning by having the better fleet, then the extra maintenance is a small price to pay...in any case, it doesn't matter, because if I had used fleet supply as the equalizer, you still are going to see the same relative differences in performance between Advent and TEC....LF's and corvettes may no longer beat out LRFs + flak, but the Advent will still lose by less than the TEC would in that given situation...I'll also again reiterate that I feel you are exagerating the early game economic advantages a TEC frontliner has...
6. I think you misread what I wrote, as that battle did not involve illuminators at all....that battle was the only shining moment for TEC, and I mainly used it to show Sareth that LRMs+flak is not the best early game fleet for TEC...I have found in my experience that cobalts and corvettes is much more effective than LRMs and flak when going against either TEC or Advent...
7. Again, I think cost is a much better equalizer than fleet supply in these cases, though obviously you don't agree with me on this point...using fleet supply as the equalizer grossly over exaggerates the power of flak and LRFs early game, which are more poweful but more expensive and time consuming to build...late game, I definitely agree that fleet supply is the better equalizer, but early game I feel it is not...my experience in MP tells me that cobalts and corvettes do rather well early game, much better than flak and LRMs...using cost as the equalizer yields results consistent with my experience in actual games, using fleet supply as the equalizer does not....
8. Demolition teams is extremely powerful, but most TEC players are still leading with Akkans, and it's common for players to only go with one cap until they get their titan...while demolition teams is more powerful, you are far more likely to see malice or energy aura in play, both of which compliment illuminators nicely...despite their power, it's actually rare that I see Corsevs used anymore...perhaps its because all the good players now play VL, or perhaps it's because the utility of the Corsev wanes once titans come out and the goto fleet composition is bomber spam...
9. I don't think the extra tier prevents illuminators from being involved in early game battles...it is a drawback, but I don't find it preventing me from getting illuminators early on if I need too...I think you are putting too much weight on the lab requirement, but I doubt I'll change your mind on the issue, it seems we've just had different experiences in MP...I do agree that illuminators were rarer in Diplomacy, but remember that Diplomacy didn't have moons (which allow you to go longer without getting 2 civ labs) and had much more powerful flak...Rebellion is much different, it has changed things, and I find illuminators to be much more viable early game with the Rebellion changes...
10. That was the point of my proposed change, that it would affect all LRFs, but likely affect illuminators the most...you don't have to agree with my proposition, I just want it to be clear why I proposed it...
11. Perhaps you missed it, but early I explained that if you go by equal fleet supply Illuminators actually beat Vasari corvettes...sure, Vasari Corvettes are the worst while TEC Corvettes are the best so you'd expect the Vasari corvettes to perform worse than TEC, but that they don't even beat illuminators is just bad...if you go by equal cost, then the Vasari Corvettes win but pitifully so for a unit that supposedly "hard counters" LRFs...
Anyway, I bring up this issue because I find in MP games that illuminators were very dominant...furthermore, I am disatisfied with the overall performance of corvettes, which had virtually no use late game despite countering 2 of the 3 most commonly spammed late game units...obviously most people don't think it is an issue, and perhaps its because I'm wrong and it isn't an issue...or perhaps it is an issue, but it's severely overshadowed by the OP Vasari or "bigger things" like the Eradica and wail...
