It wasn't until trying Sevagoth again with his prime that I realised I've been missing out
So with his new fashion (love that lopsided scarf) and more importantly his newish augments he's really become a frame that I love a lot more than I thought I would. After looking at some youtuber builds the option seemed to be distinctly nuke or ghost but honestly he works great doing both (even with some mods missing)
Overall he ended up being a frame I can play however I want.
Tanky enough to just melee or shoot when I want too.
Nukey enough to handle base steel path even without subsuming roar
Able to transition to shadow form pretty much whenever I want since the nuke instantly charges death well.
Able to nuke well in shadow form too.
Its also just awesome to be able to have swarms of killer ghosts to summon on a whim in both normal and shadow form.
