Coz they threw a bone with legendary daggers (not so legendary tbh) because we felt left behind during cata, now we're left behind again, players are really losing their patience with GC's behaviour of trolling rogues.
Comparing mage to rogue seems a bit blaspheme to me, mage is great for raiding in any spec (try to raid as subt with rogue), all specs play very differently, all of 3 have strong aoe and cleave and mage's output is 100% player effort, there's not a 25-30% of dmg output granted by autoattack and so on...The only class that can be considered as stale as Rogues are, is Mage. Yet, Mages have the luxury of simplicity where despite having a boring class a person can cope with it by making an effortless display of vanity in terms of performance and limitless effectiveness.
