I only played AION for a matter of weeks or months.
Flight within the game disappointed me, since that's all people raved about (pre-launch).
But the thing I always liked about AION was gliding. It felt pretty good, but didn't make you impervious to the environment, was instant, and wasn't some oddly shaped horse.
Did any other MMOs ever do anything like gliding, and do it well?
Spec'ing properly is a gateway drug.
