Ult is just plain OP and most likely impossible to implement.

I think a wall that blocks all projectiles is pretty broken too. I mean it renders the enemy carry usless if placed correctly. And it isnt even CC so he cant QSS it or dodge. All he can do is walk around it and by that time its probably gone anyway.
