Atma of the crab was my worse atma piece to get. I grinded fates almost solo cuz i played past 11pm to like 10am (11 hours ish).
My server time goes with pdt i think so that's why i don't see atma/ town areas populated &
No PF parties, no tells/ shouts.
Grinding at that time is somewhat great cuz you'll have no other ppl zerging down other fates across the map but my only gripe was that there was too many boss fates/ sahagin fates.
Takes like 6-10 mins to solo a boss fate as a whm
( with choco )
Some could say i was really "crabby" that morning when i got it. Lol
