Atma: only FATE "participation" matters?

Is it really true that you can still get an atma to drop for only hitting one mob in a FATE to register "participation" and then leaving?

That it doesn\\'t matter...
What medal you get
If FATE succeeds or fails
If you stay to completion or not
?

I\\'ve read different things on forums and am just wondering if there\\'s any consensus on this.

I\\'ve gotten to 8/12 on atma by seeing every FATE to completion, but am wondering if I\\'m just wasting time by doing so since I often see atma farmers leave FATEs early. Sometimes after just one action on a mob.

Don't think it works on failed fates but almost no fates fail in atma zones.

yes you can get atma's for doing just enough to get bronze but noone is sure on failing. well i say noone but someone might have done the tests and have a experiment based answer.

you only need to use around 10 skills, to get gold anyway.
so use 10 skills, then go away.
there's no reason to stay after that and cause the fate to finish faster, unless it's a boss, or there's not a lot of people in the zone.
I usually just do a few combos, then leave the fate, and i get my gold medal when the fate finishes.
You can claim multiple fates at the same time, so just go from fate to fate, doing a few combos, each.
If you're on a boss, do a few combos, then just AA or stand aside. If new people are incoming, stop DPS and allow them to get a bunch of combos in too, so they can get gold.
If you get 1st hit on a boss, you're kinda guaranteed gold, so you don't have to do much else.
Sharing is caring, dont be greedy :)
