Once the outer towers have fallen and the waves are constantly pushed in the inner towers, i find it to be game over. You can't keep up with him, you can't splitpush vs him and even if you are able to 1v1 him he will just retaliate to another lane.
What am i supposed to do? Like, sacrifice an inhibitor tower to force a baron 4v5?
He is a pain in the ass to deal with especially if he is premade with one of his carries or his top lane, cause if they communicate well, you have 2 lanes getting hard pushed.
Basically, if you fall behind it's game over
P.S please consider tuning down demolisher rune
