Oh, also, WF does indeed have a 1 minute cd. But you aren't going a minute without WF, it lasts for 20 seconds, so you are going 40 seconds without WF (max active time 1/3 of the time). In dangerous situations if you need a little more time, you can hit skill reset and get another another 20 seconds out of it, for 40 seconds total run time. If it takes longer than 40 seconds to escape danger, you are probably doing something a sorcerer wasn't designed to do (not that OP sorcerers don't do that all the time), like tanking 20-30 dungeon mobs at once or CI boss.
I have a non-OP sorcerer. Has less HP, only 41k HP. Mostly die in CI when tanker dies or i accidentally wander through the mobs the tanker is tanking and get aoe death. Which usually doesn't happen. I'm squishy, but my sorcerer is an rdps class, so I keep back from mobs so as not to get hit, as that would mean death.
