Precisely. Notice its only a problem when its a support. In all fairness, if I felt she was overpowered, I’d be all for a nerf or some sort of adjustment but from what I’ve seen thus far, as someone who tanks and heals, I wouldn’t even consider her that huge of an issue. It’s just that she was built to shake up the meta and therefore counters people like Tracer, Genji, and dive in general who have occupied a spot in almost all levels of play in some way, shape, or form. That has ruffled a lot of feathers.
Yes its going to be difficult to dive or play the staple flankers if your opponent has a Brigette guarding the back line. That is the whole point. I adore playing Mercy with an attentive Brig on the team. However I’ve had no issue dealing with her either as Mercy by keeping out of range and making sure to focus healing whoever she’s targeted until her cooldowns are spent or as Orisa by using my alternative fire to keep her at a distance and making her waste her CC when I’m immune before shredding her into nothing. As far as DPS go, Pharah, Junkrat, Soldier, and anyone with a bit of range on their abilities can deal with her so long as they don’t try to Leroy Jenkins the enemy frontline.
I actually find it rather funny how much she punishes people for not playing as a team or for refusing to adapt. Don’t swap off that flanker? You deserve that mace in your skull. Not peeling for your tank or keeping them healed? You deserve to get smashed around by the enemy when their shields fail and they inevitably die. The only unfortunate thing is that when flankers etc refuse to adjust, its the person on your team stuck as tank that is going to suffer the most. It can feel absolutely pointless to play Rein or even Orisa against a Brig and Doomfist combo if the rest of your team insists on not playing to counter them and support you but that isn’t the fault of the hero. That fault lies with the community.
