Bleed as a whole is too strong as a supplement damage source, to the point where it is defining how good a playable can be. Things that normally rely on just raw base damage such as Cerato and Alberta all switch to bleed based attack due to the overpowered state of the current bleed system. And playables that have built in base bleed such as Sucho, Conca, and Spino often rely on just that one attack for the same reason.
So what makes the bleed broken? What makes it broken is how quickly one can stack bleed and how quickly the damage racks up with only a couple of hits. The current bleed system makes you take bleed damage every second and heal bleed every second as well. However, there is a huge gap between the two values for each playable. Attached is a document that explains it further and provides suggestions on how to fix it due to the character limit on these posts.
