I always try to use ice walls to split the other team. More often than not tanks will charge in first so you can isolate them, kill them easily and then clean up the rest when the wall falls.I swear, it annoys me more having a Mei on my team then against. If you're gonna play her, know when to put the fucking ice wall up and when not to, you fucking detriment.
Sometimes the mouse placement can be wonky though.
I've yet to have a good Hanzo on my team in rank. I'm the same with Genji, I try to stop him as Mei but when he starts jump dashing everywhere it's hard to keep up with him.Had a really good Hanzo yesterday. But seems like 99% of the good Genji I see are always on the other team, and always dropping ults on us like every 30 seconds.
Tracer just seems so mixed. Every once in a while I'll see a REALLY good one. But usually they are just annoying as hell and randomly spraying people mid gunfights
Sad to hear the game isn't that much better in the upper leagues...
