On what difficulty level did you finish? 
Just Savagery without Chaos mods looked a bit sketchy to me that’s why I tried to use some MIs and supported skills by them. While keeping the theme of 2h shooter of course.
But I may be wrong and maybe these are not mandatory. Also Vit Savagery from Packla’s Skins with target build devo could be something to consider.
[edit] oh I forgot the build in question uses Doom Bolt as well not only Savagery. That will definitely help. Could also level using Doom Bolt guns just like here
just Savagery instead of Cadence.
