in regards to the RTV server, I've noticed that the map listing and rotation has a tendency to change every couple of weeks. Now I don't know if this was an experimental thing or what.....but I kind of liked the "bi-monthly" changes or whatever they were. Sometimes there were only 4 maps, other times there were more with 1 or 2 custom maps. Personally I liked not knowing what to expect each time I jump in there, rather just having a whole slew of maps where usually only a couple get played.
Not implying that ppl should be forced to play a limited number of maps, but I do believe it spreads the wealth when it comes to introducing new players to maps they may not otherwise be exposed to. It kind of bugs me to find out that someone has played INS for a decent amount of time to find out that they jump into a stock map they had never seen......due to only playing the typical most popular.
