Trash mouse being braindead gives me an easy 50% I'm happy everytime I see his dumbass.Peppering you from a completely safe location with high-damage, unpredictable, braindead pressure is often indefensible. Yes, he can be countered, but most team structures don't permit that, and it's irritating having to pick my character every round specifically to counter Junkrat, because there's always some fuckstick playing Junkrat every round.
I'll give Zarya another chance (Hate her gameplay but love her design)
You should love her gameplay most of all. Basically hit her when the shield is up and she gets stronger, shield your allies she gets stronger. http://xboxclips.com/Dr+Snipe/3e9d73ce-5b7f-4195-9a2f-df2abdc880d8
