Farming the RB levels 95 and 100 should give us a 10% drop rate for winning an Arcana. I think the drop rate is closer to 1%. My guild has been farming these things for almost 2 days, and many of us have not won any Arcana, and some have won 1 or 2. That's with maybe 200 bosses killed. Figure 20 peeps hit on each boss, that means with a 10% drop rate, we should get 2 for every boss killed. That's not happening.
Instead of @ 400 Arcana, we have a total of 80, and that includes what we had before RB started.
Gree, it would be nice if you could fix this before the event ends.
