I dislike this idea of genericity.
I prefered the school system.
I kinda agree.
In order to make the skills as generic as possible they got... well... extremely generic. Fairly useless. Uninteresting. Spending combat points isn't fun. The only reason why necromancy is so useful since it's pretty much bugged, triggering for everything (each weapon, spell, surface, effect) causing way more heal than intended. The rest, not worth it I think.
I much rather have them be their own class again and interesting to buy than boringly generic.
