Illusionary Weaponry: added the following functionality: "You have +5 armor for each Illusion Magic skill you have equipped."
This came too late.
It's like nothing is effective unless it does party wide damage so all we're doing is playing off the "AI's" lack of intelligence to spread out. I think it would benefit everyone if they improved the tactics of all NPCs and set GW apart that way rather than disrupting the consistency of skills and players builds. It says something when you can play through the entire game with one build and the same 3 heroes with one or two skill changes.
I'm coming from the point that in D&D if my dungeon master said one night "oh btw Fireball doesn't do splash damage any more monsters tend to bunch up".
