Yep.
I was considering playing a FS in a new campaign. Main reasons had to do with flavor, and the fact that in all my years playing DnD, I've never played a caster. Thought it would make things a bit easier, being a spontaneous caster with limited spells.
But, seeing what a FS misses out on kinda ruined some of the flavor ideas. NO domains? Kinda harsh. One would be nice. No swapping for Cures? So much for those extra spell slots. No turning? Forget about half the interesting Cleric options out there. I can live with the latter, but taking all three for spontaneous casting? Meh.
I was looking for simplicity, but the FS doesn't stand up. Makes me wonder how the Sorcerer would have fared if it weren't core.
