This game has many problems right now and the most blaring one currently is medics. Medics in their current state are very much game breaking and they need some tweaks to their kits.
To start they have the best kits in the game at the moment with their speed, strong weaponry, instant revives, incredible healing and the ability to revive infinitely. Most of these traits are pointed at Aura however the other medics have some of these problems as well.
Aura for instance has one of the strongest shotguns, high speed to hop and dodge with ease, a healing station which might as well make you invincible as well as instantaneous revives that can be used infinitely.
To correct this i suggest that the Developers put a cooldown of some sort on revives. It shouldn’t be extremely large but enough to make a player have to think about reviving as appose to just spam reviving.
I 've encountered many situations in which ill have dropped several players, and do to the time it takes to finish a downed player with a gun, an Aura can simple run by and revive them all making what should have been a clean sweep into the exact opposite.
Another solution could be to draw from other Mercs and make it an inventory type ability like Nader. A medic starts out with, lets say 3 revives and can do it instantly and nothing else changes. After that point it’ll function like Naders launcher, you will have a cooldown which will stack back up or you can use it every time you get one back up. This will also stop the spam of heals and put more emphasise on strategy. Should you keep your heal on cooldown or save up for a big push and revive multiple people at once to ensure you take an objective?
Now as for weaponry i feel that shotguns should be moved off the medics and onto the heaver Mercs. It is to strong to put a highly powerful weapon, that rely’s on a player being in close with an enemy, on a Merc with some of the highest speed in the game. A weapon like that should be reserved for the Mercs that are tanky and whose role it is to sit back and defend or form a wall for their team to push forward. Swapping shotguns with subs will put medics back into the role they are meant to be in, a supporting class. As of now they simply have to much going for them and I frequently see medics, especially Aura, heavy teams that are nigh unkillable, do to them reviving each other infinitely, and also have the damage to slaughter an enemy team.
In order to bring the game into a more stable environment these changes should be made to properly balance these aspects of medics but there are many other tweaks that should be made on them individually. This is also not to say they are the only problem; the lack of effectiveness of some Mercs like Arty, Kira, and Fragger, oveverall gun balancing, minor map tweaks and bug fixes this game has much left to work on. The balancing of the medics however should be the Developers first priority.
