Is mercy nerf fair?

I don't main mercy that much but mercy is a bit annoying when she fly away and goes byeeeeeeeeeeeeeeee bitch like bruh i got shit aim but like uh i gave up on it and started playing her for a while and now i can't get bitch when i play mercy xD she is dummy fun to play i don't see why players think she is boring i just ult and fuck all them up.

that was a huge nerf, but in my opinion now it requires more skill to play her with the new revive mechanics

Weakened. I'm not happy. It's harder XXXXXXXXXXD

Mercy is still strong, but now she don't need to hide when she has ultimate

I dont believe so. but i also do. they explain that mercy as she is can resurrect 7 players before her alt is gone. which is a little OP
