I'm not quite so pessimistic myself; but that being said, the really funny part is that one of Rogue's abilities is to jump on the monster's head and stab it. Assuming - which is dangerous - that this actually updates the character's position, that forces him into any circular AoEs for the entire duration of the ability. So... you know.... don't use that on any Cyclops, Chimera, most Trial bosses, Peistes.
