Honestly, I was initially in the "Riddle of Earth Sucks!" camp, but having used it for a few months, I think it's the best designed and most satisfying feature SE added to Monk this expansion. Sure it doesn't prevent you losing your stacks in every situation, but it's not *supposed* to. It allows for there to be some skill in finding/optimising where it can be used in contrast with Tornado Kick, and encourages knowledge of a fight and player skill. Like, using it between the pushback of Decicive Battle in v4s, and the Holy hit so you can get a few extra seconds of GL to refresh it with a Coeurl move when he comes back (really satisfying to execute). Or after the last boss of Rabanastre jumps when he does the pulsating AoE. The skill has uses and it's fun to find them. When you can't use it to keep your stacks? Use Tornado Kick. That's why that skill was put into the game to begin with, and that's why we still have it.
