The arena maps are a lot more fun than I thought they'd be. They're pretty fast paced, but they definitely require teamwork. One thing I also noticed was it definitely makes the medic's Kritzkreig far more useful than it is on other maps. Sometimes you don't have enough time on the map to get a normal uber, but I was charging Kritz just about every round, and even if you take out one or two people with it, that's helpful to the team.
Sadly, it seems either the server or the map are having issues. I know there were a couple times there where my entire team crashed. I crashed a couple times myself. Morbo told me he was getting errors, but mine just froze up.
Anyhow, had a lot of fun testing it out tonight. I'm looking forward to seeing how these work out with full teams and people starting to figure out some strategies. Thanks for the server, council!
