Again… you’re sitting here comparing a one shot that happens from a range uncontestable by 99% of the hero roster, just needs a headshot and has no cooldown so if she misses? Oh well just try again.
To the guy who has to actively put himself in danger to do the one shot AND needs a wall, so people can position themselves to where they won’t hit a wall. (yes that’s possible, I do it literally all the time when playing against a doom). And if he misses, he’s most likely dead if the enemy team is awake.
There is no comparison.
