Rein and Zarya, mercy and pretty much any support. is there a point in any other tank when zarya and rein do the best job out of all of them? Zarya has a cleanse, 200 effective health, and basically more damage then a solider when above 70 power, and can pop it on any ally in danger in an instant, on top of that having a game winning ult.

Rein has a massive shield and can soak up damage better then any other tank pratically, getting near him is a death trap unless you have enough damage to kill him before he swings twice, and another game winning ult

Mercy is a bitch and a half to ever hit, can REVIVE someone who died, and since her entire job is healing she does it better then any other healer on a single target.

What is the point of any other support or tank besides these ones? Cause yeah doomfist and ball CAN be annoying. but one nano and their instantly dead.
