yes and no. yes if it is your first time on that particular game's server, no if you are a regular of that game's server. i.e.
if you always liked the conditions and rule-set (player limit, possible victory conditions, map selection, etc) of the Charr'd Earth game server then you can always play on that server and get to know the people that frequent that game type and thus get to know the other "regulars" of that game server in the process, but you could also opt to just hop around from game type server to game type server, thus randomly bumping into people.
