Not sure what happened, but heatbox groups are terrible lately. You spend half an hour trying to get a group, then everyone sits around asking where to go, then you give them a location and they ignore it and go to a non-weather mutate, then they get about 15 into the chain and run off immediately after a lv40 Fate. Then 2 people leave.

2 hours later, you're sitting there with 0 boxes wondering what happened. They're actually fairly decent for light, not sure why no one does them.
