Just checking if it's not just me, McGinnis being able to spawn a massive wall that you can't destroy is very annoying to play against. She can single out a person pushing and dominate a team fight with the right usage of this ability.
In almost every other game I've played a wall like this can at least be destroyed by dealing enough damage, but nope. You have to wait the 5 seconds or so for it to go down.
You can get around or over it pretty easy. I don't think I've ever tried doing it to the wall itself, but double-jump-mantling things has gotten me over it right away.
You can't double jump mantle the wall, it's slightly too high. Triple jump yes. However, even then it forces you into a more vulnerable position just to get a sightline.
Ok. I wasn't sure. I haven't attempted it for the reason you mention, the manttle is a relatively long animation so you don't want to do it while someone can pour damage on you.
Instead I've been using the surrounding verticality in the environment to play around the wall, which IMO is totally doable. (Though depends on the hero you're playing)
