Actually the argument I was making around stealth was that while rogues are the kings of stealth it isn't exclusive to them. Same could go for mobility. Hunters (even on live) are the best at mobility, it is their niche, but a few others (Warlock/Shaman) have some "knock off" ranged mobility in the same manner. And unlike stealth, they enhanced the playstyle of these classes greatly, both of which (Destro and Ele) had a history of struggling in PVP due to a lack of mobility outside of high burst cleave seasons.
