Was playing a bit of Icewind Dale 2 before I made V'heress, and diviners in that game have Evocation as an opposed school. When I started V'heress, with "subtle" as his theme I went looking for the specialisation with Evocation as an opposed school... and it was my first discovery of just how much Bioware seem to like Evocation - you can NOT choose it as an opposition school.
Is there anyone else out there who doesn't think brute force/power when they think of wizards and magic? Modern times have artillery, they don't have timestops and similar interesting stuff

So then, i'm curious. Can this sort of thing be changed, or is it hard coded stuff? Again, note the theory nature of this question and don't shoot me for making impractical suggestions for Avlis, mkay?
From the player point of view, it's easy enough to fudge - simply don't use evocation spells
