Blade Dancer is best class for PvP. Backstab Blink Strike, 1 hit melee to the back, side and sometimes front. QuickDraw, this perk is, in my opinion, the best perk in the game. Instant weapon switching and aiming. Arcbolt grenade is amazing for finishing off anyone who runs. The sticky Arc grenade is great too. Blink, this is self explanatory. Arcblade is second only to the Sun Breaker hammers.
