Palace of the Dead, jump potions, or in my case leveling all 2.x and 3.x dps jobs to 50 one month then going so long without using them you can't remember a thing...
If you are thinking of trying a (new) dps job, and have one you don't know how to play that is sitting at level 50 or 60, in your opinion is it better to
wait until the new expansion drops then learning your way up to max level with the new changes in place?
~or~
go ahead and just learn some of the current rotations well enough to hit 70 and (re-)learn with everyone else when the new changes hit?
