Make a new role called sniper or Oper instead of making a duelist or sentinel's abilities around Oping. Would fix most of the stuff.
Everything stays the same but
Ult kill creates an orb that turns into a slow field after 1 second, enemies can shoot out the orb to prevent it
tp 25 second cooldown if cancelled, 45 second if actually used/shot out by enemy
Maybe make ult 2 bullets but you get 1 back on a kill but i dont think its necessary
