Overload champions suck lower the time in-between stuns. Big maps are not an issue. Small maps suck seriously, stun them do little to no damage on 1st stun then that blink/teleport and push and can't be stunned for 5 more seconds, and I sult it takes 38 bullets in 2nd stun, also they are pushing crazy fast up ur bum and can one shot you.. make it so once they blink/teleport and start pushing they may be stunned again.
