Maybe it's just me, but the sorcerer seems like it's only half a striker.
When originally defining strikers, the designers focused on two things: High damage, and Maneuvering.
Sure there are some close blasts in there, but that's about it. The +Str/dex to damage is an always-on thing.
Compare that to the rogue, who must position himself to gain combat advantage, or the warlock and ranger, who are forced to maneuver to make best use of their prime shot, quarry, and curse abilities.
(That's why I'm surprised by folks who suggest that this class might be hard for beginners. This is like the fighter from previous editions. The even/odd thing might get forgotten, but not as often or as consequentially as combat challenge is.)
