I believe I read on the forums somewhere that there used to be a cap but it was heavily complained about. Don't take my word for it, I could definitely be wrong. I think a friend's list could be an easy way to get around things like this. You can get on with friends easily and together help people out. Seeing which servers your added friends are on, etc. It could help with general moral, seeing people that actually work together...working together, and attempting to get others to work together.
