Seriously if its lag then its probably because your computer can handle the amount of players on your screen or in your general area. Otherwise TT is the best day of the week because even in off peak hours you can find fights easily and their are people on to defend bases and its just twice as good as what it is during the other days when two areas are up......
and when my mouse icon disappears (and no it wasnt because i pressed the N key) I had to close and restart my game (alt f4) and they open blue arena, which has 7 people....so now what can i do sit around while my plane flys autopilot for find a fight??? but with TT i can log off get some things done and still be confidant that i will be able to log into that arena in an hour.
If they are going to use two arenas just have them both open at all times with no cap and let the players decide where they want to go...instead of forcing players to log into an unpopulated server, because this is not what we pay for. I can go play by myself in offline for free, but thats no fun so I choose to pay and play with other human users.
