Orange and blue arena scores are scored under the same score sheet, so your squad can play in either one and it won't hurt your scores at all. Orange isn't "always the one" with the low cap. They are "dynamic" and adjust automatically. When you see orange low, check back in a half hour and it will have bumped up, due to the Blue arena filling.
The LW arenas were split because HTC saw too many people canceling their subscriptions, possibly due to people hating having to fight against the big hordes, or the ganging that was going on, who knows, but they felt it was driving people away with the large numbers in the main arenas.
So they split the arenas. Hard cap was 450 for all the arenas. On a good night, one arena would fill to 450, and the other would have 50-100 people. How would you like to log in and find out your squad was in the full arena and you couldn't get in? Would they switch over to an arenas where they was nobody flying just to fly with you? Would you have fun flying against only a few other people? (try EW or MW some time to see if you would)
So the "dynamic auto-adjusting cap" was born. Now The arenas stay even in population (thought not in side balance), squads can and do jump to the other LW arena to hook up with each other, because the numbers are about the same and the fun is still there.
Yes you have your opinion, and that is fine, nobody told you to shut up. "Titanic Tuesday" is HTC answer to the people who want the one super sized arena back. I'm sure its a test. If the community proves to like it, and HTC "numbers" look go maybe he'll make it available for more days, who knows. It was never a "hardware issue" The equipment HTC uses runs great, and it has been stated that the arenas could run with 1000 players in EACH and not tax the system. No its alway been a community issue.
