Look at it like Diablo II. You have your fire sorcs that do a steady amount of moderate damage. Then, you have your lightning sorcs who can do from one damage to high damage. No one makes lightning sorcs on Diablo II, though some people do get stasis because that takes a fixed percent out of a boss' health---and this is a steady damage, nevertheless.



On a side note, what's your job? X isn't whatever you want it to be, X is your luck.
