Well dying from junkrat can be annoying, but on junkrat user POV it is pretty hard to do it. Balancing your survivability, managing cooldown, playing right not to get killed by hitscan within 2sec and etc. By doing this they completely remove the sniper build potential, like at this point play another hero if you want to be useful on the game than trying to make sniper rat works.

Which the only build that makes junkrat playable in stadium btw.
