I don't know about you guys, but from mine and my kids' accounts, I've noticed a huge increase in red character pulls over the last 24 hours from rare souls (and magus, warrior, etc.).
Maybe they're trying to help us beef up for the sacrifice event? Would love to hear if anyone else is experiencing this increase. I almost never pull reds, I've pulled 3 in the past 24 hours, and my son pulled 2 this morning off of 2 rare souls from his soul hoard.
