As it is, the most magic armor you can shred in a single turn, without Source skills or hail strike, is like 400 with savage sortilege crits and 6 AP (magical poison dart, fireball, fossil strike), so I don't really see people chewing through magic armor in one turn later on.
Don't state your guesses as if they were facts. Going into the final fight dual wielding earth/fire wands it was quite easy to do over 600 damage with 6AP of attacks. No skills, just plain old wand attacks where the earth hits first followed by the fire.
I did not guess. I went in game and tested it. Of course wands do decent damage, but it's just that - decent. You did, in 6 AP, what a warrior would do in 3 and a ranger would do in 4 from the same distance.
A CC'd AI cannot use skills.
So what you're saying is, that in the High Judge fight, you were able to CC every enemy in the room, on turn 1? Please explain and post video evidence, if you can. I am genuinely curious.
