Lol, you attacked me first "you are if you want to play optimally, we arent all blessed with being in a guild of semi-crappy players that cant out dps an arcane mage like you tho", there are your words no? Why would u call someone semi-crappy if you do not even know people in my guild. Maybe show some logs to prove how strong and amazing you are? If you can't do that then just sit in your cave and do not come back.
How doing 100k dps less can slow down your progression, you won't even feel the difference between doing 1kk or 1.1kk dps. Furthermore, I was playing with many Frost mages, and I haven't seen a single Frost mage who would make me feel bad about playing Arcane, especially during progression. When frost has to do mechanics his dps is not so great anymore. Moreover, Mythic is all about doing mechanics while not going below dps check, higher dps comes later. You sound like a guy who clears content only after he outgears it by miles so he can skip most/hardest mechanics by simply skipping them by doing high dps . But oh well, FoTM players are always like that, they trying to hide their lack of skill behind strongest classes in the game
