tanking

I always use RR as one of my atmas for the DD aspect of it
stuff like Shiren Shadow, Cloak and Dagger, Einherjar (Sobek mostly), etc, basically w/e the situation calls for

if theres a tank and dd is more my focus

RR
Apoc, VV, alpha omega, GH, etc (GH pretty standard for me to as it works nice with RR and Blade: Hi)

I've never really set up to just nuke but stuff like

Minkin, Ultimate, MAB INT bonuses etc
