You must be watching the wrong usual global channels, because as I type this there are two trials forming in Cim, two in the RWZ2, and three people are forming Moonfires, and that's just in LFG/TFs/VU.
edit: Things are slower at 6 AM PST when I get up for work, and slower also at midnight on a weekday, but trials and WSTs form all the time.
So yeah, it seems that I delayed too long on getting all my Incarnate slots maxed out, because now that the new-content smell is wearing off now nobody wants to do it anymore. So I end up loggin on periodically during the day to silent airwaves and the occasional calls for STF. The usual global channels are dead and trying to use the LFG function is like waiting for God to deliver a woman to my doorstep.
So since every other major piece of content is run on a usual schedual, have we established a time or day to run WSTs or Trials?
