Supports have too much survivability
90% of my matches I play supports, and all of them I’m with the least deaths on both teams, I know that support don’t need all this sustain, just to focus on awareness
That’s not a problem, because for example moira and brig are not problems
But when you give it to problematic characters like bap and Ana they become immortals beasts
As for the cauterize, it is to encourage playing closer to cover, make healing tanks not painful out of combat, and at the same time not making players being healed so hard to kill
