Xtyger, the All channel was dumped by HTC a while ago bud. You need to tune to channel 200 to talk across all countries. Even then some folks are not tuned into 200 chat. There is a way that you can talk to individuals on their private vox also. I believe this is a fairly new option.
Virage, The way things have been going, base capture and win criteria are still somewhat debatable in added benefit to the Axis versus Allies arena. Even with base capture and perk points virtually unimportant objectives of the arena, folks still resort to griefing behavior such as vulching airfields for the sole purpose of, I don't know, entertaining themselves at others' expense, or landing "kills".
The most important aspect of this arena has been the "air combat" featuring side specific rides (you don't have pony pilots on the same side with LW pilots). Not everyone that visits the arena understands this. To complicate things, whenever field capture is an objective, vulching is an "acceptable" practice to allow troops to enter the maproom and suppress defenders of a town. This pretty much forces two things that don't promote air combat. 1. Large suppressing forces outnumbering defending pilots. 2. Sneak attacks avoiding radar contact in force to surprise unaware defenders.
