New LVL 15 Class Quests Need to be Added Before Being Allowed into Instances

[Raymeo]

How many guildhests are there anyway? I've only seen 3, and I've talked to all five battle wardens.

There are 14. Two for every five levels, beginning at level 10 and ending at level 40. You only visit a Battle Warden to unlock the first one. After that, finishing a new guildhest for the first time will automatically add the next one to your Duty Finder list. This will continue to be how you unlock new guildhests until you have reached level 40 and unlocked all 14 of them.
