Seeing as you're looking at the self-stagger on the Hate incarnon, just to mention that the Ack and Brunt incarnon has the same issue - when I'm using melee I'm constantly using slide and jump-slam to reposition and I'm ending up self-staggered to the point of the incarnon 'ult-mode' being a downgrade... Please fix this one too!
Also a few Kaithe QoL suggestions:
1) The ability to customise the Kaithe somewhere other than Teshin's cave - in the arsenal vehicles tab perhaps?
2) The same three customisation tabs as we have on every other item (Kaithe currently has only one). :D
