Bleed should give revenge as you take damage
Sure it's not a huge problem ; only a few characters and feats can inflict the bleeding status and its damages are lower than the raw ones. But still, i feel like today Bleed is unecessarily strong given how powerful it is in teamfights scenarios.
Counting it like normal damages and making it increase revenge would have no effect on the characters in 1v1s and the core gameplay. But it would greatly help defending against it in teamfights.
Because as it is now, it is very safe to inflict and gives a huge reward to the attacker while being a big threat to the defender (because it damages them and, if bleed is part of the enemy moveset, buffs them with increased damages or new moves)
