Let's take stock on these

>Faust
Situational, probably will be mostly useless since he even has the Heisho's defending for him if he's about to take attacks.
>Ryoshu
Easily the best one here, just straight up more damage, no contest.
>Outis
Sounds good on paper if you haven't really been playing much rupture, but rupture already shits out so much count you don't really need something like this
>rodya
More potency, always nice to have. Probably the second best one here.
>Gregor
Kind of depends on how his own poise economy looks like, ironically enough the Heisho team can also make use of Ryoshu's nebulizer if they really need more poise.
