I hear you, it can be hard to let go sometimes.
The fact remains, Jaina's WF kill had two Warriors, that's not my definition of a wheelchair class. In BDA we're not in top shape, but looking at melees we're ahead of the curve in a supremely melee-unfriendly raid when it comes to DPS. The situation isn't amazing by any means, but acting like it's the end of the universe is silly, balance comes and goes. Warriors have had a top-tier DPS spec in every raid since HFC (Where Arms dominated until Nighthold where Fury took over, Arms became great again in ToS, and in Antorus Fury was superb, and then in Uldir Arms was top). It just happens that BDA is a raid where split cleave is king and melees are dogshit at that, on top of Spriests and Warlocks being overtuned. Shit happens.
