Although the full round casting rule denied them quicken, I've played sorcerers and the ability to use any of your metamagic feats on the fly was astonishingly useful (Oh, I'll just make my Suggestion spell into a Silent Suggestion on this occasion. I'll empower this false life since I think we're getting into a particularly dangerous part of the dungeon).
