Whats the rest of your roster look like?

I am not sure you've got a UNM team in there.  I certainly don't see a one key UNM team in there.  Who are you running for NM and what kind of damage are you doing per key?

33 m damage for 1 key nm

Post the rest of your roster. There's definitely pieces of a full team there, but I need to see other stuff.

Have you tried playing around with Fahrakin?  I used to use a combo of Counterattack & Ally Attack to do 2-key UNM.  If you swapped Fahrakin for Aniri, it just might get you enough damage to get to one-key NM, which is a step in the righ direction.  Depending on the strength of your gear/builds, you might not even need to use Lifesteal since you have BEK in the mix.
