Raid events will be changed starting 2 Raid events from now. You'll only be able to get Demon souls from Experts and Ragnaroks. Furthermore, it looks like Ragnarok spawns are much more frequent so they become more time-consuming to complete (because fewer join). That event's Expert is also a pain, so it's difficult to get people to join on that one also. The overall effect seems to be a repeat of what we saw in the first Raid event: newer players with weak teams struggling and hoping someone will join their raid. I was never fond of the PP system, which rewards endless grinding, so this seems like an improvement to me.
