Sorry SE, but endgame won't work if you don't fix something.

actually demon wall is pretty straightforward, it's always center, side, center, side, repel. You can preemptively stand on the safe lane, or stand just at the border, that way lag won't easily get you. When it comes to the adds popping, you still stick to the same routine, make sure your dps can kill them fast enough (one can LB for instance) after that it's pretty simple.

you can shift + F to focus on the demon wall, this way you can see it cast repel even when you aren't targeting it. It would also be a good idea to level THM to 26 as that grants you swiftcast (instant cast any spell).
