I agree with you, maps are too big even for 128 players, so here is my tip, create a Portal server on small conquest, the maps is smaller and you can reduce the number of players as well. I did it, it was way better even more in terms of fluidity!
I like the map sizes but even with 128 players a lot of the time it seems empty, I'm thinking it's to do with the flags being made up of a main and two sub capture points.
If it was like it used to be with just the flag to capture then it would be carnage in a good way.
Also i reckon more transport vehicles like quads would be good, although the call in system is ok i guess.
