Because in PF, there is nothing to tell whether the other people in party will eat orb or not, and don't know how many they will do also. So it is confusing sometimes that tank need/should eat more or less before making it into 3 stack buff. (you could eat a few and wait the cd reset to eat more than 3 if the party need you to eat more).

So I would like to ask that usually what would be the default set up of the amount of orb that tank need to eat in each phase? Or is there any good method to sort out problem of party member vs tank eat orb too many/ too less ?

Also, since the amount of orb spawning in each phase are fixed, I wonder if anybody has schedule up the amount of eating per rotation yet?
(for example: )
rotation 1: ST eat 3, dps eat 1.
rotation 2: MT eat 3, dps eat 2.
