Unairu it´s still the worst focus tree

That tiny buff to it´s armor passive it´s useless, i tested it againts a butcher lv 100 and it only provides 15 extra health after 3 hits on a Atlas with 1100 armor, also the return damage passive does nothing, it´s sad that all other trees got something fun and usefull than unairu.

Most of those sound like bugs, and some of that sounds like you only tested it in the simulacrum, probably with a sub optimal build. 

Good feedback is also a little more descriptive, there is barely anything on your post that can help identify any issues.
