ohk melee is with a super with scorch charge so thats fine by me. sc should ohk since striker is the melee class. now the wambo combo is a grenade plus melee ability and envenomed slows, removes hud, gives crap visuals, and does DoT then you toss an aoe grenade that you can't escape because the smoke bomb slows you down by so much. on top of that you can double the effect and time it last.
