My general thought is all spells should be available, but if they're not set, you don't get the stat bonuses, trait combos, don't work with JAs, and have tripled MP costs and like 300% increased recast times. There's still a lot of stuff you'd never cast at 99, but it'd still be nice to have a slightly larger library to work with.
Quests requiring ilvl tier gear to complete could also be used to up the set point cap at 99.
Violence good. **** bad. Yay America.
