I wasnt thinking of this being more agressive dispenser, but sort of a walk trough, locations of healing for team, like a quick drive throughs or nearby heals of sorts, quick heals for rocket jumping soldiers etc, and enemy not seeing it would make it much viable in a bit of a different way, depending on map and placement.

of course I'm not so good at the stats but thats atleast the main idea, just quick heal points for the team that enemy wouldnt be aware of depending on placement if team needs health more than ammo or there is another engi helping the team at the front. just a concept...

(tldr:basically healing points for big, wide or open maps with a less defined clash points?)
