Give him a watch that allows him to teleport a short distance in the direction they're looking by right clicking rather than turning him invisible.
Pros:
- Cool movement
- Would immediately be banned in all competitive modes due to being broken so u wouldn't have to deal with it
- Edgy pubbers would lose their fucking minds and because you can literally teleport behind people and so more people would play the class, thereby buffing it.
Cons:
- You will receive the funny backstab when playing pubs
Alternatively u could give him a trebuchet so he could launch himself at people or maybe some sort of fart attack which does poison damage to nearby players and propels himself upwards. What do u guys think?
