Nat. The best is Nat. 
Loving FL4k myself. I’ve been playing him in pet spec for a while and it is really fun.
What is a ultra?
Action Skills
End game tvhm mayhem 3 it dosent matter what modifiers Brawler ward Moze is the best in game for dropping bosses and mobs alike. Fl4ks crit build is beast but against mobs it lacks and Amara is fun but her builds are super gear dependant and just to me do not stack up with Fl4k or Moze. I truly believe most of Amaras trees are broken and do not work properly. I haven’t used Zane yet
AMARA…say it with me…
Or…
Amara tell your friends…
Her lines when she kill someone…
