Who is your most hated counter and how do YOU play against them?

I feel like I can play pretty well against almost all counters at this point. The only one that truly rage baits me is Scarlet Witch. Whenever I get killed by one and watch the replay, I can literally see her cross hair half way across the screen from where I am and I get genuinely upset lmao.

Knowing I'm playing one of the highest skill characters in the game and getting my health MELTED by a no-skill dumb stupid fucking legal auto aim cheating character pisses me off so bad.

She, along with Peni and maybe White Fox are my only bans in Comp I go for. At this point I can play against Namor pretty easily and don't even worry about banning him.
