No, Why are the named modes being played the most? cuz ppl enjoy them. I see many PvP mode which also get popular at times.
But as per the suggestion, yes its annoying sitting in room nums greater than 8. This is why i tend to perhaps kick out afker or single player in a room or wait for rooms 1-8 to open up before making the room. Having 4 more possibilities on the 1st page is a good idea.
