Personally, I always really enjoyed the SiC Naval Strike server back when is has 48 slots instead of the current 32. I think 48 was just right for most naval strike maps to have a bit of infantry, but not too overcrowded as on some Naval Strike matches with full 64 player servers. 32 is just too few, as a large portion of each teams 16 players will be in vehicles, leaving a few to be very lonely infantry.

In addition (and a bit more general) I really miss servers on conquest small, obliteration, capture the flag etc rotations.

Also the wacky servers, like Zombie mode and other plug ins.

Btw if a lot of people agree on a certain thing we could do a communinity event of some sorts and revive such servers/rotations for a while. Since the game is so old i think it won't happen any other way now unfortunately, and ift would be a lot of fun.
