Support more than ever are brutally targetted in OW2 due to the many map flanking changes and the lack of shields and a tank, and the uberization of the main tank.
Countless support have complained, say they play less, or they choose “bad picks” because they favour the survivability.
So even if stronger support didn’t draw people away from other roles (which is rubbish imo but whatever) fixing those issues will have more support playing and will have support playing stronger support characters.
It’s difficult for them to give support straight up more dps ability, because what you’ll end up with is tanks/dps abusing the support queue to get a quick dps fix. But they can add survivability, be it movement, stuns, knockbacks, escapes, invluns, anything that address survivability.
Imaging an over the top change where support were given tank health. Suddenly dps flanking to take out a support isn’t as viable. it would take too long and they’re squishy and a well coordinated team will punish them, or even a support with decent aim on their damage will win the fight. But pressuring support will remain the viable strategy becuase it distracts them from healing and allows a team dps or tank pic while they are distracted. Throw in escapes and the same is true.
There are things they can and should do.
