Trying to get Baptiste ult achievement

It’s only really going to work on escort or hybrid maps, but I need a support to help heal me and the DPS, tanks that I can heal through my ult while the DPS (preferably Soldier 76 for his ult, and a good Ashe or a Junkrat) fire through it for 2.5k damage/healing combined.
I need people who are dedicated to the strat and are willing to try multiple times as this achievement is a pain.
Higher your skill the better, this achievement isn’t easy. There’s also the cheese strat of healing tanks from spawn on attack but that’s difficult with 2-2-2 unless one of the DPS’ is a Bastion maybe? idk…

If you still need it I can help, I am working on some achivements too.
