I do think the gun performs pretty solid if used correctly. Curse mastery and ebon armor pair extremely well with hyperos. Pressure crush can do crit damage, so any arcane abilities that buff crit chance (if you need the extra crit chance) pair really well with the proc too. Deep squeeze triggers on normal attacks, so going for haste will make the overall dps of the proc stronger too. I'd say tadthep is probably one of the best arcane abilities to use with hyperos since it buffs the proc in 3 different ways: haste, damage, and crit chance. I do wish deep squeeze can also crit too, but that might be a bit much. The only issues I have with the gun is the proc chance feels all over the place and having to do pressure crush for the proc to work.
