We instead, for every merc except Medics, we each had two syringes.
This syringes when used, would heal you, gradually of course, not instant heals, but heal you nonetheless.
The reason I am suggesting this is, you can choose to heal yourself, or, if your allies are low on health and out of syringes, you can pass them one, allowing them to patch themselves up and you get Support XP.
“Why is this needed?”
Because there are two very common problems in the game currently, one, is the distinct lack of certain mercs or resources. You are not always going to have an Engineer, or Support, or Medic, so having a soft counter measure to this would help somewhat. And second, health regen does not kick in most of the time when you really need it to, especially if you’re the only one holding an area down and don’t have much support. This will allow you up to 3 bars of health, two from syringes, and one from when you spawn of course, after that, you’re dead meat unless you get more syringes or get a Medic.
“How does this affect Medics?”
One, Medics can supply an infinite amount of health, so you’ll never run out, two, their heals are still instantaneous. Compared to these they are still superior. And three, since Medics can heal themselves with their abilities this does not affect them at all. They still maintain a high degree of potency with faster revives, more health on revives, and an endless supply of heals.
“Wouldn’t this encourage more solo play?”
Did you miss the part where you can toss syringes? Think about it, everyone can plant bombs, everyone can revive people, but the distinct difference between these general abilities, and the more specialized mercs, is that they cost time, and have a distinct risk when using them. This is just the same, when you are out of syringes you are basically unable to heal yourself.
