haven't actually bothered timing the drop rates to be certain, but it kinda feels like they share the same timer. When going after the Garudites, it feels like at least 3 minutes between each drop of either Breeze/Garudite (and these are mobs consistenly granting 105/111 xp to 99, think that's around 81/82 now). Might have to actually start timing them out of curiosity.
