Just a copypasta from the Steam Forums to get more feedback on this suggestion.
There are currently “incapacitated” indicators for Medic Mercs (Sparks, Aura, Sawbonez) when other allies are downed, so that they know who to revive and when.
In that case, then it’s only fair for the Fire Support Mercs (Kira, Skyhammer, Arty) to have “low ammo” signs above allies that are down to their last magazine. Just a simple Quality of Life improvement that hurts no one. Right now it just feels like I have to throw around Ammo Packs everywhere since I can’t know who is in dire need of it, unless quickchat is spammed.
Meanwhile, Medic Mercs have all the information they need on their UI. Rarely does anyone ever need to spam quickchat commands for healing and revives, since the UI displays ally health and that “incapacitated” indicator when they are downed. Once again, it’s only fair that Fire Supports get a similarly informative UI.
