if u nerf his E ability he will be fine. He should not be able to send missiles to the entirety of hookah in bind, thats like a better version of a brim ult for free. But his abilities seem balanced. I am sure his E will get nerfed in a week or so
drone can supress but you can just shoot it so
the stun is very situational and its worse than a breach stun since u have to throw it and may not always land where u want it to
ult is great for sure but not game breaking
I think he will replace Breach in all Breach maps because he is basically a better breach with a drone, but the fact that he doesnt have rechargable info util might be his biggest con. you still need a Sova in most maps i think
