Or the Gunslinger Hunter who runs around with cranked strength, Knife Juggler, Gamblers Dagger, and armour effects that give extra grenade energy for knife kills, extra super energy for grenade kills, and weapon effects that grant grenade energy. It's actually a much faster grenade/super regen having it that way than having well-balanced stats. The strength is there for the occasional miss. 100% effect to strength gives a very fast return on any missed knives, and Juggler grants a free knife on precision knife kills.
