(edit: my mistake -> Oct 29th 2015 update does NOT boost DOT in all the game)
Woops ! Yesterday it seemed that Cathy (one of my siren) was melting loaders with her Hornet as she has never done before in UVHM. Then, I did some weapon testing on the target dummy in Sanctuary, NOT knowing anything about the game update. I just noticed that the damages dealt with the Hornet was incredibly and dramatically increased. I was astonished.
This is just an effect of the last game update (dated Oct 29th 2015). Some Maya skills in her Cataclysm tree have been boosted: Cloud Kill, Helios, Backdraft (?!?) and Blight Phoenix (only with Nov 9th hot fix). Maya has finally “regains” what she previously lost with UVHM: damages for some skills not scaling well with with (high) levels.
Consequences: possibly new Maya builds using skills that were considered as “waste” (Helios, BackDraft, Cloud Kill, Blight Phenix… to mention a few). The Cataclysm tree is “revived”.
Thanks Gearbox for this update that brings a whole new fresh wind in the gameplay.
