Simple. Every Class gets a melee healing ability (as an exotic arm piece of course). How it works: If your team mates health is very low and about to die, you simply just melee him/her and they regain their health very rapidly! To stop people from abusing this healing usage, the melee counts as an actual melee, meaning you'll have to wait 30 seconds for it to recharge! Simple idea and will be very effective when playing in close proximity with one another in a nightfall/raids! Please give me feedback on this. It's such a simple idea!
