Removing buffs/ debuffs barely happens in this game, as others have shown. It's probably not important given the state of things, but dispel is actually to remove buffs from an enemy, rather than removing debuffs from an ally (like leeches, esuna, and maybe sometime in the future erase). Doesn't really matter though because I think only MNK has a dispel ability and as expected it cannot be used anywhere that matters (in PvE).
