That always annoys the piss out of you? Okaaaaay.
The truth be told, I didn't know you were new to the game or whether you were a vet with a new handle... either way you clearly weren't aware of its existance. It's not in rotation because of its size, not because it happened to have a single field at 10k in the centre. When I started playing, the arena would only hold 200 IIRC and 100 people online would be the most I would see.
The idea is sound and made for some great furball action, as others will (and do) testify. AH really was a blast then and there wasn't any of that long-distance-can't-find-a-fight nonsense.
Oh yeah, I haven't been here from the beginning. July 2000.
