Remove the need for a target when casting smoke screen.
This is a small change, but i think it would make the engineer much more fun to play considering you can use it to stealth. I think it would make the mechanic much more fun when you can have an on use stealth which doesn’t require you to be in the middle of a fight.
I know you can use the smoke bomb, but it’s just too slow when you want to escape, also i dont like bombs.
