Kick will cost zero energy in patch 5.2, bringing it in line with most of the other melee interrupts in the game. Ghostcrawler indicated that as PvE utility ability, Kick should be free to encourage regular usage. In PvP situations, Kick was already the straggler in the process of becoming free, not the forerunner. Blade Flurry's new 4-way 40% cleave allows us to deal 260% of our normal melee damage to 5 targets. Combat's cleave is still quite potent against two targets, but now excels when facing small groups.
In addition to these improvements, Smoke Bomb is learning a new trick. In patch 5.2, Smoke Bomb will reduce damage taken by our allies inside the Smoke Bomb radius by 20%. While Tricks of the Trade has always been a valuable addition to our arsenal and we have several buffs and debuffs, the new Smoke Bomb is our first true raid cooldown.
