I think the last poster must have been in the wrong place. Spawns are less than 18 minutes apart. PHs I saw were a Bloodmoon brawler, a Bloodmoon warlock, and then popped the Bloodmoon Warlock.
took down this mob today lvl 80 necro and 79 druid dropped girdle of wirlem and also a gem covered box easy kill really with druid healing does summon which is a pain
