Plain and simple, she shouldn’t be able to buff damage as well as heal by simply changing button to click, they keep nerfing heroes because… Surprise surprise, they outperform when they have a pocket mercy, like YO maybe, but maybw, the problem is mercy, and no, decreasing the buff would simply make her useless or very very boring to use

I would say that to fix her the buff is either replaced by a defense buff or larg helaing projectile that when it hits it creates a cloud of helaing for allies that lasts a little, so she can heal far teammates as well and the ultimate could become a mix of both heal and buff at the same time so she doesn’t lose that aspect of her, and she doesn’t need to choose if she wants to heal or buff during ulti.
