Seems weird that a couple people saying their flagged for all 6 and their hasn't been a 7th hammer kill yet. Im definitely in! Cromis can you confirm is one person in each group needs all 6 trials completed or everyone in raid?
Some time ago Delorne and maybe Rholo organized this as an off-night in-guild event, many/most of us are flagged for it. It's not a progression target, so really not scheduled for raids. Temerity has a real RL > all approach so getting the numbers for an off-night is difficult, and to be honest the gear available is not any better than what is more easily available elsewhere, so the only real motivation to doing it is because you want to.
The trials are short and straightforward, the event itself is easily accessible, one of those perfect events to open up.
All of us had a blast doing the trials; short, fun, something different. Hope everyone else has fun with it.
EDIT: Everyone in the raid needs to complete all trials.
