Small balance changes you would make

Brimstone: One smoke recharge after all bought smokes are used
Phoenix: When the Ult runs out, he stays where he is, and can now press X again during the Ult to cancel
Deadlock: Trips alert you no matter what, but only stun if enemy makes noise
Iso: Delete from game

Thoughts?

Deadlock change is honestly pretty good, I really like it.

Brimstone change is decent, but having four smokes is kind of OP if you're not playing slow

Not sure what you mean by "stay where he is". Canceling ult is a decent change

i like everything but im not big on the phx change

brim 4 smokes would be totally balanced because it would only be after 3 smoke have been used

Just give iso a viper wall and jett dash and killjoy turret tbh

Iso: Give him the double tap shield without needing to shoot the orb, doesn't die if he loses in ult and only gets like a small penalty (loses his shield or something), 2 Shields and make them a bit wider, his vulnerable is honestly pretty great so keep it like that

This will then make him a niche pick lmao

iso: make it so if he dies in his ult he still survives, so either nothing happens or he gets a kill

iso needs the speed boost on kill more than clove
make his wall curveable like harbor
his vulnerable is too telegraphed, like they know ur gonna swing right after u toss it - either give him a nearsight, or make the vuln curveable or have a non linear trajectory like phoenix

chamber: trip is only visible at a certain range + shoots faster
iso: make wall able to be stopped like harbor, give shield at start of ultimate

bring back yay chamber good old day!

brim would be op if that happened.. imo his smokes are fine.. they're the longest and you cant see inside it too
