as the new change in trait and pistol
here are some example of leeching abilities (was discussed in other forum)
most will say the trait change 5%-8% isnt worth it (i might agree as you see i dont use it in this vid) also as sole minor buff to your hp
but all in all leech abilities can work nice even with d/x as now it hits 2 target
there are few more build options
p.s
i try it few time against warrior meta builds and didnt work for me at all, but against other builds and classes 50% success (i need more practice with this set)
