Just because I haven't discovered a trick to make the AI give away their gold or a spell bug that makes my unit unhittable doesn't make me bad or you good.
If you can't win above Challenging you are not at the "haven't discovered a spell bug that makes my unit unhittable" stage, you are at the "haven't figured out to use maces against chain mail" stage.
In the .982 AAR you may notice that the first time my fortifying guy and my blinding gal met was to take out a Shrill Lord on turn 67. Before that, I did perfectly well without using a combo (fortify+dodge+blind) that works a bit too well.
I also think that it is not too much to expect that IF
1. I pick a race defined by its fortifying ability
2. I retrain a spell casting sovereign as a dodging assassin.
3. I dress him in a robe, skullcap and give him a one-hander to maximize his dodge
4. I recruit and train a death mage, and give her a staff, a mage robe, and a emerald skullcap to maximise penetration.
5. Get ready for the fight with two healing elixirs and a bag of pork.
THEN
I may expect to actually have a chance to take down a single monster that's threatening my city... provided it does not hit me too often. In that fight, I used all the pork, was down to one elixir, and the mage blew through 60 mana dishing out damage.
You call that cheese. I call this playing the game as intended, and pointing out, as a good little beta tester, things that the developers MAY want to address. Personally, I think Blindness should gradually dissipate.
And, by the way, if the only thing you took with you from that AAR is 'Blindness makes you unhittable"... Well, I guess you have nothing to learn, do you?
