Locking, muting, and playing.
Start a match, lock in your hero, mute your team. Is this bad practice if you want to avoid other toxic players? As a returning player I feel like I am done trying to compete with other players and their choices. I just want to play and have fun. Further, is saying your role at the start of the match not the same exact thing as locking in?
I feel like the amount of interaction between players eventually degrades based on the quality of the match. If you do good then you are praised, if you do bad then you are reported. Why not eliminate the chance of having your account suspended or worse by muting? Would it be good standard to tell your team that you are muting them? As interaction is still possible through pings?
