This may sound like hyperbole, but Buer can do something which (afaik) few to no other characters can do. Specifically, she can pop out potions. Popping out potions isn't free. It consumes a chunk of her health, and if you want to pop them out faster, it consumes even more health. However, as a general rule in a longer battle you will get 1-3 free potions, and the rest of the potions she makes you will have to use to heal her own HP. However, the 1-3 free pots alone makes it worth bringing her along at times. What makes potions good is that they aren't as limited as other healing skills, which tend to heal for relatively little, especially if they're SR heals. Potions on the other hand easily heal most of your health back up. But as if this wasn't enough, Buer ALSO happens to have a group AOE heal, which has a short CD that she can reduce even further by sacrificing her own HP, something few other healers can do. If she only had the group AOE heal, I would already include her on a list of best SRs just because of that. However, the combination of being able to make potions and heal your entire team really solidifies her as one of the best SRs in the whole game (imo).
Generally speaking, it's better if she isn't the one being targeted, but if she is, you can use the potions you generate to heal her, in which case she helped to mitigate damage for your team for free, similar to a tank. Either she's mitigating damage for your team by being targeted and healing herself, as well as pumping out occasional aoe heals, or she heals somebody else who gets targeted. One way or another, she adds a lot of sustain to a team.
I haven't tried her yet in labyrinth, but if she works like all other characters (CD refreshed for each new battle), she is going to be insanely broken. Starting at floor 1 you will be able to generate dozens of potions at no cost whatsoever.
