To be honest, I'm glad they didn't wasted much resources on Ultimate which most of the players never will experience anyway. Boss fights in this game are simply boring (no matter which difficulty) and take way to long for the little rewards they give. How long usually a Savage Boss takes? 15min? 20min? Sounds like fun lets do Ultimate and beat the same Boss in 30min. for shity loot.

Seriously if i want fun and challenging long Boss fights i play something like Monster Hunter or another MMO.
