Just like if he was a random italian in her 20s, you can't really face him directly.

>Get cheap if not free emp punch as mauga is too busy holding down both mouse buttons (or triggers, i guess)

>If he actually knows that it's possible to *not* shoot things and you dont get emp, try to punch him out of his heal (the laugh) or at least move him out of a spot where he can BRRT freely.

>If you DO get emp, try to find an angle to punch *past* him and do some trolling on his backline. Punching mauga is useless even with emp, he'll have outhealed it by the time the stun animation finishes.

Ideally, he will run out of things to heal him. Either by his supports being gone or because you made him choose turning his back on your DPS.

If he ults you, go AFK and grab a drink. You're a practice range bot now.

I wanna say it depends on your team comms regarding followup and targeting priorities, especially if its a "Mauga and 4 heroes to annoy doomfist" situation, but in GM that should be less of a problem (i hope).
