SpaceGhostsCoffeelanskytry to play a round of mge without letting go of your push to talk bind as an example, for most people this will be very uncomfortableI can agree with this, I still use my side of the mouse push-to-talk, but when I am in mumble with friends mgeing, if I am talking a lot during it I will do noticeably worse. It might be some combination of being distracted and holding my mouse differently, but it is noticeable
I had a friend I used to mge a lot with and when we played out of mumble he'd usually dunk on me. However, when we were both in mumble, talking having a good time, he'd stop having good movement and always strafe to his left. I asked him if his ptt was v or something like that and he got confused and asked me how I knew. IMO m5 is the best way to go since shift can be used by other games.
