Nerve Strike is a good talent, but it doesn't take an amazing talent to be always chosen when your choices are Combat Readiness and Deadly Throw. Post shuriken nerf, it's almost impossible to land a meaningful DT interrupt, and roguewall, while good, only turns on versus physical guys. Nerve Strike has been the go-to peel and defensive move, and it's been quite a bit above in every season except the first one- and only then because rogues were like tissue paper, and roguewall was kind of needed a lot.
Regardless, it has floated until now.... when we suddenly hear it will be nerfed for the final season. It hasn't gotten a lot of attention, what with warrior charge being turned into a root (it has been a stun since like alpha?), but it's a very strong nerf. It is literally being HALVED in power- that is a hell of a lot of reduction.
Why was it changed? Was it because it was too good in tier? Probably not. It certainly wasn't because of the overall power of rogues, the only class not to show up at Blizzcon for even one game, and with well below expected rep. It was probably changed because it was too good AND it was annoying people. But, nerfs to power level should be compensated with buffs, unless you want the power of the class to drop- and rogue class power doesn't need to decrease.
Also it is one more dumb difference between pve and pvp, and yet another failure of the talent system. Whatever, at least we still have shadow blades.
