The cap is likely only reachable during the Odin and Behemoth FATEs so what would be the point of channels? You want SE to waste time and money for something that will only be used for 30 min stretched a handful of times per week. Some servers probably won't even see the cap. I am curious about teleport fees and logging in though. In FFXI the cap was only ever seen in Beseiged which was technically an instance so logging in in al Zhabi just kicked you to Whitegate.
