I do think sniper as a risk forces teams to pop into certain lasts. There was a point in whatever discord pug group when sniper was banned, and in response, people just started brazenly milking through certain doorways during last pushes. EX:Snakewater last top left, Sunshine top right, Process 5. Just tank a soldier to 300, and brute force your way through the door knowing that the defenders can’t commit enough resources to really stop you (or you will uber and kill the fuck out of them).
Obviously, there is still the risk of a sticky trap, and soldiers do have the ability to stuff some of those doors to force teams to pop while being able to escape, but it’s yet another added responsibility for soldiers who already have the burden of having to stop point, keep the flank from getting in for free, etc. IDK maybe it’s just skill issue and top players would have a different perspective on it.
