Healing Herbs Overwrite themselves

[sharkinajar]

It's kind of really frustrating when you are a red star defiant, get hit with a 1 hp / round herb from an ally, and die due to not being able to heal.

Pleaaaase make it so when you use an herb on yourself, instead of the "cant heal someone being healed", it overwrites the previous instance of herb healing.

I personally would be a proponent to allowing the fighter perk heal be on a seperate cooldown to the other ones?
Its a bit unfair to ask a player to choose between having ANY burst healing or being able to do damage.
