Help for the build

Hi guys,

i played ED+contagion last leagues and the feeling of the mechanic is something i simply can't give up. Bane seems really strong and i want to try it so i'm asking if there's any point on building a trickster with ED+Contagion plus Bane (ed/contagion for pack of mob and including bane for bossing?)

Sorry for my bad english, not my native language.

Thanks in advance guys!
