If you like standing still while blasting away, BLM fits the bill since that's pretty much their play style. Though since you still have to dodge aoes, you'll have to learn to maintaining your dps while moving to be good at the job.
Or do Bard, their much shorter cast time makes them more mobile for the times that you do have to move (which is quite often), damage isn't as good as most, but their utilities make up for that. While they do have a good number of ogcd to weave, they dont have many gcds to worry about. (In fact, with Iron Jaws, refreshing your 2 dots is now 1 button!)
