As part of the pre-Mists patch 5.0.4, in August 2012, hunters were given Readiness as a baseline ability. Readiness is a carbon copy of Preparation, which has been a rogue workhorse for years. While I am typically hesitant to give hunters any more ink, there's something interesting for them in the patch 5.4 PTR notes. Readiness is being removed from hunters entirely, and their cooldowns are being rebalanced to compensate. An ability that was considered so crucial that it was made baseline is being pulled completely just a year later.
Cooldown management has been an integral part of the rogue class since day one. Preparation has been our go-to PvP ability since its inception. The entire World of Roguecraft video series was predicated by how amazing Preparation is. A rogue with full cooldowns is a deity, a rogue without cooldowns is a pushover. When Preparation was made baseline in patch 5.2 (January 2013), I was certain that the once-optional ability would be a permanent part of our arsenal. Now, I'm wondering if Preparation's next on Blizzard's chopping block.
