Tom clancy the Division's smart cover is brilliant! Medics now have a deployable that has everyone in the area recieve a 20% resist shield. Gives exp in the format of guardian exp. This would be good for the game because it mitigates infantry dying to quickly to explosive spam. Value can be modified. Trophy system from cod might be another good format for what I'm trying to implement.
Medics already have this, it's a shield regenerator, also your deployable would still die to explosive spam
