Turn it down to 64 players...

Yea maybe you do but really i think it depends on a lot of things.

I don't suffer from any lag in any game mode and especially 128 player maps no lag.

I play on PC with 10ms to EU servers and it's as smooth as a babies bum.

My £5000 PC and super fast internet means i also get any vehicle i want at the start of the round.

That's M.2 SSD gen4 4Tb @ 7000+ mb/s for you......

If there is any lag spikes i haven't seen them apart from end of round or something else like the rocket exploding.

Cant say ive really experienced lag that wasnt my internet (PS5, Europe) but I would say that I welcome a reduced size to 64 players if the maps are changed in scale to reflect this or at least give the option in the server browser update.  As it stands I never feel like Im on a server with 127 other players and dont feel like Im in a team of 64 people.  

The scale of the maps feels like they were designed to accommodate a lot of vehicles and not a lot of players, they are very large but worse, they are extremely open with little to no cover.  At present, you could easily scale the map down say 20%, move flag points in and have a lot more cover options to provide ground forces with proper battles.

I'd also like to see a return of some maps with actual streets and buildings to fight in and control - BF5 maps for example:

Operation Underground

Devastation

Rotterdam
