if doing it on raids and depending on the raid and number of shm on raids there are diff ways to use ancestral
I used to think it was strictly for the dps increase aspect of it
on some raids thing mgbs for the healing aspect seems to be more beneficial
doing mgb cr, wood, aid, paragon as a preset grp protects entire raid against massive ae (dd and dots), dead toons do no dps at all....
there are times when u have enough of a certain class and u need specifically a dps boost and u go that route
just popping tranq and mgb just because they are up is never a good idea, raid leader prob gonna make requests when to use them
