Our current player inclusive world bosses use to crash the servers, crash peoples clients or just dc everyone on the map. I'm guessing, if we keep the same system, it's just going to happen again with new bosses. Also I personally get no joy out of mindlessly aoeing an invisible boss with 500+ players around. I don't understand how people find it fun. New bosses don't need to have a two hour spawn time(it could be less or instant), or be so hard that only a few FCs can kill them(although I'd be down for that). There just needs to be some sort of player limit and a 24 hour(or so) lockout after killing it so everyone can get a slice of the pie.
