Hmm...
Interceptors need to be able to take out fighters, so they would be anti-very light. If they themselves were very-light, that would make sense in that they would counter themselves and would be taken out easily by flak. They need very little health and/or low armor. That said, they would still beat up on LRF's. I guess another counter to the darn things would be nice, but still... These things for the TEC lets say, need around 4-5 AVL damage per ship if it was a squad. On the other hand, making interceptors so that the Advent only had 5, the TEC 3, and the Vasari 1-2, it would make more sense. That way, you could still have them deal high damage overall, but would be easily killed by flak. Flak burst would no longer just kill two-three SC, not you are killing the entire squad which yields a much greater drop in DPS...
I like that idea...
As far as super-caps go, or SotL's as you would know them from the thread, the heaviest classes are structure/module and capital. I believe module is slightly heavier, but that is more or less irrelevant. Currently, the assault cruisers deal good damage to SB's. Since these would resemble them in many ways, it would make sense to give SotL's the same armor class... Just give them high health/armor and it would work...
As far as the damage they would deal... They would need to take out SB's as well as capitals and HC's. I can't see them killing anything smaller on a large scale, so just make them deal AVH. That would yield a good rate against all those things... Give them around 150 DPS to begin with and max of 600 DPS at level 10... That would make them cap killers but would require an escort fleet of frigates to kill off the LF's/Illums/Torpedo Bombers/Assault Frigates the enemy would use against it...
I do believe this would work...
Its simple, but effective.
