I documented a 4 hour wait and sent it to Hitech. I've had no reply to date. This happens more often than you'd imagine. I can open and close AH repeatedly trying to find a point where I can get in and the arena where you guys are will range in anything from the exact cap to 50 over the cap. It is not isolated. I got discoed yesterday and then gave up trying to get back in when the same thing happened for 20 minutes.
In all my years of dying in AH, I've never not been able to get into an arena. If the squaddies are that important, maybe they'll move for you.
Conversation on squad usually goes something like this.
"Hows the fight in Blue? It's looking kinda poor in Orange"
"Got a good fight between two fields here. Come on over."
Next thing you know, I've got wingmen.
If you are sitting around for 4 hours waiting to get into a particular arena, I'd suggest the problem lies with you and not HTC.
