@GVlXxf I do think it needs to be a challenge to bring down the heavier aircrafts, and some way to boost certain characters for the task, like Support class in BFV had slower overheating. I was initially sceptical of the aircrafts OP after the Beta - which is typical of any BF title - but since i have seen videos of helis being taken down with both sniping and grapple hook. Sniping is fine, but grapple hook is a bit silly IMHO, and should be reduced/removed in favor of upping the AP ammo damage.
A full string of LMG AP ammo in a Nightbird makes almost zero damage, and even if it prevents the self healing, it is just not good enough. A full clip of well placed AP LMG ammo should at least be enough to scare off a nightbird, after all it is supposed to be Armour Penetrating.
