I was "disconnected" at the time arena mode was introduced. When I got back online, nobody even played it anymore. It's a shame, because I really like it.
I would be in favor of a good arena server, seeing as we would have the only one in Europe we certainly would have some players. The last time I played I had to go to a shady Russian server, because it was the only one with a decent ping.
I'll voice Demm's reply too,
I also enjoyed Arena a lot, but too many people didn't like it, and I could almost never find any SpA people to help me fill it,
and seeing how there's no one out there, I'm guessing there could be room for one in europe.
and it increases my interest in TF2, since I'm tired of the normal play, and some times just can't be arsed to start it at all.
