Aatrox Dive
You can learn to work around it as I have....
However, every now and then I get really pissed at it. If you don't let the enemy hit you with their dash or engage FIRST, then you are dead. If you dive before they even start their action but they hit you while you are in the air, you get knocked down, and now have no dive to use to escape.
Literally everything swill stop his dive. Its super annoying, his engage is probably the most easily interrupted engage of all champions.
Heaven forbid that this dive is not interrupted by ground=based moves, like a ground pound. No, that would be too much to have Aatrox dive actually counter certain CC. What ever happened to counter play?
Fuck Riot.
