:/ I hope you don't change it to much. Really, the only thing you nee to do is have the players MaxHealth slightly replenish overtime.
Drop the regular bandage in needing to replenish the MaxHealth bar and use it just to stop bleeding.
Want to heal your MaxHealth faster? use a medicalBandage, medkit, eat, drink and so on.
The need to use a 'bandage' to recoup your MaxHealth, even if you are 'Not' bleeding, is what's confusing people and the crux of the problem.
You need food and water to replenish your MaxHealth and Health overtime? Logical.
You need a 'bandage' to recover your MaxHealth even when you are not bleeding? Not logical.
