I need some help! 
I'm contemplating a class that takes longer to cast a spell than normal...quite a bit, actually. Most spells that usually take one standard action will now take one standard action...plus a full-round action.
What I'd like is some opinion on how this spellcaster would still be used, if at all. I'm preserving it mainly for flavor reasons, so if it weirds stuff out too much, I can ditch it, but, in general, how important is spellcasting time to you guys out there? Would a round and a half be too long to wait between fireballs? Cure wounds spells?
Feats will exist to offset this (one to reduce it to a full round only, another to reduce it to a standard action), but this is spending precious feats...
Is it still worth it to cast spells, if they take that long to cast?
