Show me a sorc/sage that can hit for 6k+. I have full BM gear and my hardest hitting spell doesn't even break the 5k medal, even with a +willpower stim, trinket, adrenal and the +expertise item in wz's. (This is only going to be lower with the surge nerf)
Stop over exaggerating numbers and making up stories because it's people like you who break games, by acting like everything should be nerfed to suit you. The truth is you're probably one of those bad players that just keep running at sorc/sages with NO strategy or plan in your play, while they kite you to your death.
Bind your stuns and interrupts, start using them and stop being terrible.
