This was probably already discussed and I apologize if this is a repost. We have currently unlocked the XP and Karma buffs for our guild members in the Guild Hall at the Tavern in Gilded Hollow.
I know Anet has stated that some buildings would be unavailable to people who have not purchased Heart of Thorns such as the Arena, but did they ever mention that Guild Buffs would not be usable to people who did not purchase Heart of Thorns?
As of right now, our guild members who did not purchase Heart of Thorns are not allowed to take a 24h Guild Boost from the Tavern.
I just wanted to see if this was working as intended.
