The soul stealing spell that kills a friendly hero to steal a spell-book from him doesn't seem like something a good sovie would cast.
Paragon doesn't seem like something an evil sovie would cast. Come on, sacrifice some of you vital stats to benefit a subordinate? They'd kick you out of the villains guild.
It's ok in the beta, so everyone can cast everything no matter if they are good or evil, but I hope they clean this up before go-live. Maybe neutrals could cast both.
I have a similar issue with the wildlands where the reward is to gain lots of hit-points, and lose ability to heal naturally, but only if you raze one of your cities. Seen any good guys lately in a hurry to massacre civilians to turn themselves into an undead zombie ?
PS: the forum spell-checker doesn't seem to like "undead". Seems like they could use a little dictionary customization if they want to do fantasy games.
