I'd like to request that Beamdog revisits how Wizard specialization is handled in NWN.
The biggest flaw is that you don't get to choose your opposition school(s) like in 3.0. And the NWN opposition schools feel arbitrary and imbalanced. Evocation, Necromancy and Abjuration are not among the opposition schools at all, while Conjuration appears as an opposition school three times and Illusion twice. Thematically, Necromancy seems like something many spellcasters would abandon if they had to choose.
So please let us choose the opposition school(s) freely.
Another thing that feels off about specialization is that it's much more about the choice what you can't do
rather than what you actually specialize in. It would be nice if specializing actually did buff spells or caster level of the chosen school, or would give the character some other relevant perks.
So maybe unhardcode the whole thing so that the community can make their own house rules around specialization? 5e has really cool ideas about specialization perks, I'd love to be able to have something like that.
