Your playstyle's going to be changed anyways, dude, what with having to pick specific elements for your enhancements rather than getting a package deal.
It's not like before where, if you wanted to be a fire sorc, your secondary element was locked into cold. Now you can get fire and electricity, cold and acid, fire and force, etc.
Considering I pretty much exclusively play Human sorcs anyways, I think I'll be able to squeeze in the necessary feat somewhere. Drow Sorcs can just focus on CC anyways, what with having higher DCs.
Not to mention Sorcerer isn't the only one whose PrEs involve giving up something. Just look at Archmage - sure, it gives you SP, but you have to spend MORE SP than you gain in order to get some of the side benefits. Everything from raising your DC to gaining spell like abilities costs SP, and guess what? Wizards actually have issues with SP :P
