Support Class / Ammo

So i normaly never use LMG or have ammo issues with M4A1 that i normaly use in what ever battlefield but now i see that im not the only one going support class with lmg running and gunning TTK is fast and lovely, you dont have the ammo problem that you have with all the other classes, no movement penalty that is something to care about, no recoil to consider.

So what im trying to say, all other classes have ammo issues. they need more base ammo to stay relevant. the TTK on the LMG is magical. its the perfect sweet spot but the other classes need to get there to for them to stay relevant. The support class have unlimited ammo, fast revive, fast TTK, fast movement, no recoil, its a really fun class and setup but it makes the other classes kinda lacking in gameplay and i think the TTK and ammo is the biggest problem
