To harrass at level 1 you slice hit once and dice away, once you hit level 2 get 50 rage slice up (slice doesnt take rage) cull to meek) then dice out or dice infront of them to to melee a few times. With my build once you hit level four. slice in with 40-47 rage stun which brings you up to 50 rage then cull to meek, and dice out or infront of them to chase. now remember at level 6 you get beefy as ****. so Slice in then hit you ult and stun ten cull to meek which should have 50 rage by then, then chase with dice with lowers their armor then cull to meek as soon as possible and spam your stun. if done right you can 2v1 people at half health.
