I've been trying to get into Orange Arena most of this morning and it's been full the whole time.
When I started early this morning it was around 103/100 and I couldn't get in, even after wasting time in the TA, then check Orange, the DA, then check Orange, Blue Arena, then check Orange. So I left for a few minutes on the Forum to check out the upcoming scenario info, etc.
Just now I spent several minutes clicking in and out of the Arena menu to watch the changes for Orange Arena. It started at 114/100, then went to 116/100, then 118/100, then down to 117/100 and back up to 118/100. We're talking about 4-5 seconds between checks for me to quit then log back in.
So how in the heck does it get from 103 up to 118 when capacitiy limit has been at 100 for the last hour or more. Just curious what the algorithmn is that runs this abortion.
