heroes of the 2nd

[Lollie]

On observation of coerthas, outer ll and S than. The fates appear to be on an hourly replenish cycle with certain ones given priority, though not guaranty that they will occur with greater priority. These priorities appear to be based on difficulty intended (not level). Lower difficulty fates also have a higher replenish amount. Exceptions to this are the beastmen item fates which appear to be on separate 15 minute replenish cycles.

Observations leading to above
Outer ll
Long periods of no fates other than the 3 beastman drop one near the end of the hour during high clear times. 50 non beastmen fates cleared in the hour followed by no fates for time remaining till the turn over 4 consecutive hours.
Quantity of individual fates were the same in that same sample period, the placement of occurrence in the fate order varied only slightly.
S Than
Applied formed theory above to this zone and received similarly supporting data sets over 3 hour periods on 3 separate days.
Coerthas (needs more data sets)
3hour sample
Fates: bellyfull, 4 winds, giant seps, eyes have it, saints wake, various trash fates.
No named region on the map had more than 1 occurrence of this level fate at the same time. Ie 4 winds and bellyfull we're never up together, 4 winds or bellyfull and eyes or seps were up simultaneously on all 3 hours. Saints wake initiated halfway through or after the completion of eyes or seps (whichever happened first) all 3 hours leading me to believe that is the top edge of the lower region.
