Medic class is not good. It is not usefull, it is not fun to play, unless you want to RP.
It just does not fit in the current game meta.
Here is a proposal for making it more useful, without changing the meta.
Support class is basically a rifleman with support boxes. Which is good!
Just redo it like the support class is done: Make it a rifleman that boost healing.
1- Make loadout similar to rifleman: Same main weapon & same munition amount
2- Keep smoke grenade only (2 or 4 depending on the loadout)
3- Most important part with first point: Give an AOE radius arround the medic to make allies bandage twice as fast when they are in the AOE of an alive medic.
4- Keep twice as fast bandaging for the medic and infinite bandage for the medic, cause yeah, it's a medic
5- Provide bandage supply box. It is not really useful, but it exists so it does not hurt to keep it
6- Make revive be full revive, without the need of bandaging
Once this is done, you will see mucha more medic on the battlefield, and you will never heard anyone complains about medic in this game
[EDIT] - Add point 6
