Cool, I also managed to get past 2.2k MMR on my alt Mage without 2 weeks of its creation with ruthless gear playing with a half ruthless holy paladin, no big deal. The only time I remember Twohard going over 2.5k (yet nowhere close to 2.6k) was during his partnership with Shizophrenla, one of the best spriests on Warmane Cata. However I'm not aware of his achievements as a Feral or a Disc, so I can't judge. However if 2.6k is easy as you claim then how come less than 10% of the PvP community are actually that high? If you know what you're doing then sure, it's a piece of cake. What you said about Twohard only means that he's adapted to the arena environment faster than Twoeasy or Abbi could, both of them actually peaked at 2.2k. I don't comprehend your "if Twohard can do X then Twoeasy/Abbi can do it as well" logic.
No, they should do so for their own good, if they don't mind being mediocre 1.5k players (1.5k is obviously a metaphor for being bad at PvP, pls don't take it literally) for the rest of their lifetime then so be it, what do I care
Sure, here you go:
