Dynamis was exactly a low drop-rate time sink but the other tiered events were done a lot better.

These fights are accessible to most people because you can retry the fight quickly without having to wait a long time, whereas most stuff in FF11 locked you out for 2-3 days no matter what, which is anything but strategic. It's why I think sky is probably the best-designed, since it doesn't lock you out of crap, takes some time, and its mostly easy to schedule around, barring needing X amount of people. Once they made most of those trigger NMs force popped it was pretty much perfect.

Moogle got beaten after people constantly throwing themselves at it for several hours at once which would probably end up being 2 months if this was FF11, and its very tough to practice any sort of fight when you have to wait that long. I much prefer it this way.
