An arcane mage in my guild is pulling 16k dps in ICC10 man by just using arcane blast until they go OOM and then doing nothing while mana regens. Of course they're doing less damage than the other classes doing 10k dps (unless its a very short fight obviously). The raid leader is encouraging the other two arcane mages to do the same thing because it makes their dps so high.
I've been trying to explain that dps is completely meaningless because its more a reflection of how frequently you're causing damage than how much total damage you're actually doing to the boss. Its damage/"in combat time." In combat time is just a completely meaningless number that gets lower(inflating your dps) the more time you spend NOT doing damage.
So all I can find are threads where people debate about the topic but of course those are filled with stupid mages defending "dps". I'm looking for a nice article that makes a clear argument on the topic that I could present to them. Has anyone seen anything like that?
