Personally I like the way Timeless Isle is set up. Maybe add a bit more and it's extremely good. I prefer the isle over dailies any day of the week. You can just go about your business, pick up the few dailies that are there and start killing stuff, regular mobs and rares etc.
You get timeless coins from everywhere decent gear for alts. And you can set your own pace really. Might be because I'm more of a casual player that it appeals to me, but the fact that I am no longer blocked by a limit of possible dailies in an area feels great for me. Now I don't feel like I have to login each day to prevent falling behind on my own schedules. If I can't make it day one, I can always spend more time doing it on another day and compensate that way.
Loving it and I hope it stays and gets expanded in WoD.
P.S. Judging by the poll on the frontpage today, almost 50% of playerbase seems to also enjoy the Timeless isle.
