As a tank, I’d rather deal with Reaper than Brig (when she was OP). Getting bashed was usually death one way or another, so like ptr Reaper, it was stay away or die.
The difference? Reaper’s only purpose is “stay away or die,” Brig was that and an off-tank and an off-support. Reaper also still has to deal with barriers and only heals while doing damage, which means he only heals while winning in close range.
Reaper also can be dealt with by tanks, Roadhog and Orisa, and any future tanks that can fight him outside Reaper’s range. Brig could only be dealt with by picking Rein and Zarya, forcing mirror matches, and Reins had little control over the situation until bash stopped bypassing barriers.
Brig had too much sustain to kill at range, even with dps heroes who should counter her on paper, and could do her job just fine even if she’s forced to play backline every now and then. Reaper is as easy to kill at range as he’s always been, Hanzo even can one-shot Reaper. Most dps have an advantage against Reaper, as always, but now he has good match ups against all the tanks instead of just Winston.
