Apparently rogues haven't been getting the message. Year after year, as punishment for our evil deeds and shady dealings, we've only received coal in our Winter Veil stockings. We were not deterred, as we simply pickpocketed good presents from everyone else. A frustrated Greatfather Winter, tired of our shenanigans, finally turned to his manager. Santa Ghostcrawler, with the rumored Naughty List tight in his grasp, set about enacting a Winter Veil surprise that rogues would not be able to ignore. A 75% nerf to Blade Flurry in patch 5.2 did the trick.
Melodrama aside, Blade Flurry was broken. While I would've preferred to see the ability spread to all three rogue specs and balanced appropriately (back to a cooldown?), Blizzard went in a different direction. Blade Flurry remains firmly a combat-only ability, but the edge it held over assassination and subtlety has waned significantly. Combat is no longer shackled to purely two-target gimmick fights, and assassination and subtlety rogues no longer need to respec and reforge multiple times per night to flex for Blade Flurry. The net effect is incredibly positive for rogues as whole, and we should be embracing this change.
