It appears the frequency of arena chests is lower in the past 2 days. Not only that, the items we need for Sirius spirits are much less frequent. I used to find several per day, now I get almost all falcon feathers or ancient tree branch. I have stacks of those, and the mithril ores and mushrooms are all but non-existant. Another slow up by Tynon I guess. It's not our fault we have to farm arena for mats, been waiting and waiting and waiting for new content.
