Not at all for PvP. Bladedancer is the second main PvP class most top players use. Insane grenades that get you almost one shot without having to aim (Skip nades), Check. A melee that can win straight up melee battles (Backstab glitch), Check. The best evade/mobility move in the game, Check. I know invis is used less but it is still a way to hide off the radar for around 10ish seconds. Not to mention the super can be great as long as it doesn't shortstop.
