Arthritis needs to scale its number of hits for activation depending on the weapon type. It takes 3 within 2.5 seconds of each other. In an Auto Rifle meta, that's absolutely nothing; for a Hand Cannon or a Scout, it's effectively a kill. The only saving grace is that not too many people are using it. It's mad that there is a one-hit kill ability with negligible setup, very little aim required, and it can potentially recharge itself [i]and[/i] Dodge. I think there is skill to the regular version, but with the Exotic it is ridiculous. What irritates me more, though, is that the other classes have no equivalent. I mean, can we talk about Gunslinger having 4 melee options that are all distinct and have their own builds, while Voidwalker is stuck with 1 that does less damage than a standard slap?
