Currently Kaze is basically a 15% boost to defence and Damage
Halfed exp from missions
And when you die you geta stupid high jail time.
Boom, all the perks to kage.
I think the kage perks need to be finished as mentioned in a patch notes thread:
Earns more inf per mission
Faster Advanced tracking
The suit also does nothing. So maybe adding it to the powered would just make things easier.
