Going against the grain, I don't think chaze is op at all.
2 characters that together work exceptionally well....
BUT.
No 'instakill' (Nihilus)
No 'screw up your entire teams cooldowns' (Nihilus)
No 'remove your ability to use 1 character completely' (Thrawn)
Fighting teams with chaze I swear at my device more often when Thrawn fractures someone, or nihilis makes my entire team just have to use basics... Or just kills instakills someone....
Couldn't give a crap about chaze.
