Forgot to add, its not a gank build but quite bursty.
Magnum Shot -> Ambush -> LA - > Killers blade can do quite some damage already, Incap strike on top and someone dies.
If people do not die you can always re-engage.
Ring of Wild hunt, Concealed Weapon leads to you being faster in stealth than other people walking around...easy to get away from people, re position etc.
