Dargons, Fun
Gifts fun.
Crap potions less fun
Full instances 20-30 minutes before spawn (sometimes longer)
means many people miss out. or you have to stand around and wait in an instance up to 2 hours.
Waiting game for a christmas event is not a good idea. turns players off especially if they have limited window to log in. Rethink.
Lower time to 30 mins or so. and you might sell more bag space from item shop as a result.
waiting for 2 hours for a spawn is rediculous anyway.
