I agree with almost everything you said, except for your first point. Here is my opinion to it:
I wouldn't call 128 players a massive battle, especially not with the current playstyle of high mobility, bunny-hopping, running around like chicken and spiderman wingsuit action. If this game would be a massive battle we would be all sitting inside some trenches waiting for artillery or airstrikes to clear the way.
The game needs to be way more tactical, not like a milsim, but it should actually require you to use your head instead of "sundance lmg brrrrrrrr flank grenade boom special effects".
