While this is a strength, this isn’t necessarily the reasoning.
The big issue comes down to the fact that Brigitte has to actively engage targets to get healing, and those targets are limited to largely back-line Supports, or flankers. If she’s dealing with anyone on the frontline; usually assisted by or assisting a Tank, there’s a good chance she’ll be eliminated quickly.
Moreover, Brigitte has an unfortunate issue of not having any sort of active self-heal she can turn on at anytime. Though she has a passive, it isn’t quite the same as Mercy’s and tends to be less effective. On the otherhand, dealing with Brigitte at melee range is challenging for a lot of damage-role heroes, as they do not have the same kind of bulk that she has.
In much the same way that Brigitte is sorta-implied to be able to take on more than a 1v1 in the same way Symmetra is implied, neither are really supposed to or are good at it. They don’t have any sort of invulnerability or escape to break off the fight. With Brigitte the implication is her extra armor, and with Symmetra it is her multiple sentries and high-end damage output.
This is why there is a tendency for players to complain about Brigitte or Symmetra being or feeling weak without really understanding that this is intentional and not actually a real problem. But rather, the issue stems from committing to an engagement and not being able to break out of it, if it goes bad compared to other heroes (See: Moira and Fade).
Rather, Brigitte’s biggest problem is Rally being rather underpowered for an ultimate, since Overhealth is now readily available via a cooldown (via Tanks) or in a much stronger form via Sound Barrier. She is otherwise, relatively stable and strong as a Support-hero.
Healing Ofuda does have a cooldown after five tags are casted. It is short, but it is there.
Repairpacks granting any extra health has been… problematic especially for non-tank heroes. Even Junker Queen’s attempt at granting overhealth turned out to be at issue, and was rotated frequently with Brigitte and Lucio supporting. There’s nothing wrong with Repairpacks at present.
This is largely false.
Brigitte has twice as many displacements as Lucio’s, though, Lucio’s is area effect compared to Brigitte’s single-target. Still, Brigitte has greater range that Soundwave with Whipshot, as well as more damage through Shield Bash and Whipshot used in combination. These are both very effective peels when used properly.
