@Miriamele: I could be tactical about it, if it were not for the fact that all that requires a crap ton of luck and timing. I've got great timing and great tactical skills but luck? I have none. And most of the time, the people I attempt to go against are easily able to avoid stuff like Frost Nova or Inferno. Heck, most of the time they don't even need to.
How about this. How about each and everyone one of you play a level 71 Mage. Go into PvP and tell me how well you do against each class. Your gear can not be godly and you can only have a level 70 green wand that is +9'd. You tell me how badly you do or how good you do when fighting other classes at your level or around your level. Or just anything in general since you can't really pick and choose in these places.
As for PvE? You can only rarely get a group. Relying on friends is a no-no. So for the most part, you're forced to solo with the above mentioned gear. Oh and no cash shop items. Again, tell me how you fare. Because if you can do better than I can, than I will never complain about Mages again.
