No problems at all getting into any arena of my choosing and just because you can't get into the one you want to doesn't mean the arena cap system is broken.
Just because you do not run into problems it doesn't mean it is not broken.
I didn't quit because "I can't get into Orange" or "can't fly with my squad"
Caps once worked, even for my timezone. Now that numbers have changed significantly, they do not work anymore. They do not split 500 players into 300 and 200.. they split 140 into 100 (large map, locked) and 40. Once we had only a one hour dull time period after caps kicked in. Nowadays, it's often 4 hours or more... our whole evening. Only on weekends with higher base numbers it still works like it used to be.
And yes, for many of us that's a huge degradation in gameplay. And no, you don't have to be a basegrabbing horder if you are looking for more than a occasional 1v1 dogfight.
