I don't have the issues with the sorcerer that the OP has (at least, I'm not sure, because there's some vague up in there), but I do have the issue that if you want to go with a theme, the spell list choices are very narrow and exclude some spell that would be very thematic but, for some reason, aren't on the list. It's very difficult, for instance, to be a thematic blaster with any element other than fire -- or, more to the point, you would have dramatically fewer options to represent your theme than the fire blaster has. While a large part of that is the overall spell selections being limited (there just aren't any 2nd level lightening spells), there are a number of notable exceptions where a thematic element spell is on the wizard list but not the sorcerer list. Given that one of the major archetypes of sorcerer is the thematic blaster under the dragon heritage bloodline, that's annoying. Not gamebreaking, but very annoying.
Elemental Evil Players Companion fixes that issue of lack of blaster spells for a Sorcerer. Not only is EE AL approved, but the player's guide with all those spells is a free download.
