Personally I dont have issues related to the ACI BF3 server, but its true, people tends to preffer servers with a better ping.
I remeber that when I started to play in your bfbc2 server my ping was good, but in the final days, my ping just grew up to 200 or more and was almost unplayable, even with few people.
Also people tends to preffer servers with more than just 4 people playin'
