As many other players already said, Aura is currently not A but THE problem in this games balance and I agree on this.
But how to balance her?
Here is my approach:
Aura:
Health: Increase it to 105
Movementspeed: Reduce it by 10 - 15%
Healing Station:
AOE: Increase by 5 - 10%
NEW! Delay: Players are only eligable to healing if they haven’t received damage in the past 1,5 seconds
Defibrillator:
Cooldown: 3 secs
On the other hand we have Sawbonez who is currently just FUBAR if you compare him to the stronger Aura.
Here is my idea how to make him “work”.
Sawbonez:
Movement Speed: Increase by 5%
Large Medikit:
NEW! Instantheal: The Medikit instantly heals 20 health. (heals himself only by 12)
HoT (heal over time): The Medikit now heals another 30 health over the course of 6 seconds. If you are damaged the HoT is cancelled. THE HOT DOES NOT STACK!! (heals himself by 23)
Maximum Number: The maximum number you can carry is reduced to 2 (you can place up to 5)
Cooldown: CD is set to 13 secs
Defibrillator:
Cooldown: 3 secs
