To be honest, I have the same "problem" as the OP.
Where I used to be able to land 3 meteor swarms from a distance and swoop up the rest with the rest of my fire based spells.
I now can cast one meteor swarm, have to wait for things to be in range, delayed blast fireball, fireball, scorch and perhaps do the last 3 a couple of times as mobs run all over the place.
If things go bad I have to jump into a pack and do an energy burst, as a failsave jump out again and do a dragon breath.
My biggest pet peeve is the waiting for things to get in range but still be far enough for them to not hit me.
Energy burst is a really dangerous move to pull of without being cut in half as a sorc.
Also my spell list is limited in what I can carry around and utilize successfully, though I have been playing around with it as some of them I hardly use at all.
