Archer/Hunter Help Rainbow Hive Bow Build Tips?

I finally finished Qira, and came up with this. Is there anything I can do to make it better, with a focus on dmg, but still with decent survivability? Bombs already do 10k, and mana regen is 9/4.

I can't post links because I'm not very active on the forums, but here's the list:

Pisces
Libra
Vaward
Capricorn
Moon Pool Circlet, Prism
Megabyte
Gigabyte
Hive Bow, with T6 Air, Earth, Thunder, Water, Water powders.

funny rainbow tank

 

I don't have much experience with rainbow builds, but I tried to add some survivability and/or damage while retaining decent mana sustenance.

Yo the first build is hot

 

A major problem with the builds I sent, though, is that the mr rolls are tight. Thus, these are definitely not low budget (RIP Memento's 4/4 mr).
