Eh not really. In a semi-small room he can be a little problematic, but I think once people start to get the timing down of his rocket punch and how long it takes to cast (1 sec) and how long the cool down is (4sec) you'll be able to keep a decent gap and hit him from a far or surprise him with burst damage up close when he is fully on cool down.
I have only used him briefly so far. I'v seen someone just whoop *** with him and it made him look fun as **** tbh. However, I have had no luck in being able to duplicate what I saw. I hope to get more time in on him soon because he is fun. Wish they would have some better skins for him tho.
Not really op
I killed many as tracer and in a quick play match I killed the same guy 4 times. Yes I did got killed here and there but when he's charging for his punch and aiming, he's vulnerable to the other attackers
