I did this meta yesterday, prime time on a weekend. There should have been several groups up on LFG at that time but only one popped about 5 minutes before. I think part of the issue ( on top of the crap rewards) is that it can fail early on if the 7 pre event areas are not completed in time, you can get away with 6/7 but people are not getting organised across the map early enough, maybe they arnt highlighted as obvious areas of focus on the map? maybe the timer should be a little longer? It also seems to take longer overall than the other 2 'easy' ones, i think it was 40 minutes.
They really did this map wrong, it was full of people fishing and no one doing any events before the time popped. It's dead 3 months after release.
