LMGs is really OP for now
It's easy to control recoil in the apex legends and that's a big problem. This eliminates the difference between different weapons and makes them too similar to use. With a non-critical recoil intensity and a very similar recoil control efficiency, additional weapon features become more significant, and LMGs have no equal in this: they have more bullets in clip, they are easy to control when shooting from the hip (especially rampage), LMGs have high damage per 1 bullet (especially rampage) and high total damage per magazine (especially rampage). In a direct firefight, it is extremely difficult to shoot LMGs - they have much more bullets and dont need to reload as often as assault rifles or SMGs, also LMGs in total need to hit less times than other automatic weapons due to the greater damage per bullet. All these factors make the variety of weapons in the apex legends quite fictitious, because controlling weapons is about equally easy, but in other respects, LMGs are simply better and more effective. Now LMGs, due to their light and easy control recoil (especially in the Rampage) and large clip size, shoot almost all other types of weapons, including weapons for medium - long range, even marksman rifles. This is not a sign of good balance.
Weapons should be created in an integrated manner, taking into account the strengths and weaknesses, but when LMGs are strong in everything, this is not a balance. Large damage and clip size must be compensated, for example, by recoil. Moreover, it is logical: big damage - big recoil. In other games (for example, battlefield and others), LMGs are much more difficult to control than any other automatic weapons, but in the apex, more powerful LMGs are even easier to control than assault rifles. That's silly. LMGs as a class, due to their strengths, need to raise the overall recoil level, and quite strongly, so that you can feel the difference in gameplay between machine guns and other automatic weapons, as well as to compensate for the strengths of LMGs as a class and balance them in the general weapon pool.
Also, it is necessary to significantly reduce LMG's accuracy when firing from the hip. At close range, even with no scope, the machine guns will shoot any other weapon due to the larger size of mag, as well as the total damage. Machine guns are really big and powerful weapons with a lot of ammo, so it's odd that they're also easy to control. This is not fair from the point of view of balance, since it gives in total to the already existing advantages an additional too strong feature, and it is also unreasonable logically, because these large and uncomfortable weapons simply cant be so accurate when firing from the hip, it's just inconvenient and illogical. Therefore, it is very strange to see how, for example, a rampage (a big and very powerful machine gun) shoots much more accurately from the hip than the r-301.
All weapons have their own characteristics that make them unique. The peculiarities of LMGs are high power and large clip size, but this must be compensated for, otherwise this class of weapons becomes too powerful and simply uncompromising. And according to this type of weapon, it should have high recoil (due to high power) and poor shooting from the hip (because these are large uncomfortable weapons adapted for prolonged shooting)
