Hello there.
I have been leveling my mage, as Frost, since lvl 1 and I have been doing pretty good in dungeons as far as dps and dmg go. Atleast that is what I believe to be true. (Please do not tell me to go fire, that is not the point) In dungeons I do roughtly about 20-25k aoe dps, often 30k when lucky with ice lance procs. From experience on most trash tanks are very high on aoe dmg, and that is not the problem.
Today I joined Stonecore and on first trash I placed Nether Tempest on three mobs, placed Flamestrike on the ground used ice lance when it procced and arcane explosion (I find blizzard do less dps when I compaire it) I was doing about 17k aoe and the dk tank did 18k aoe dps, we were just at first trash and I wasn't fully ready and the rest were doing less then 10k dps. The tank then started to flame at me saying that I should go single target because my dmg sucked. the healer was shocked and told me to ignore the guy, prob bought his char at ebay.
My question is, is the tank just rude and I should just ignore it and that I am playing alright or am I doing something really wrong? It really got me upset, because we only did one damn trash and he started to flame me.
