BLM unneeded skills

[Dzian]

Thunder 1 is a core of the job. You should always use it.
Never actually cast thunder 2 or thunder 3 save them for thunder cloud procs.

Aetherial manipulation is also a great skill. its an instant warp to party member. which essentially allows you to finish casting your current spell and then warp out of whatever telegraph you're standing in. much better than interrupting your spell to run..
often proves invaluable for keeping enochain up. when you really need to move but really must get blizzard 4 cast off. finish the cast and warp out of danger..

blizzard I don't use that much unless I totally bork things up and need it to trigger umbral ice and get some mp back.
