Hunter's Board idea
I don’t have a Hunter’s Board, but find it odd that you indeed can’t get a mix of material types. Would definitely be good to have such an option when you aren’t looking for anything in particular.
Honestly I always found those home-instance gathering nodes not to be worth it. You’d have to gather daily for over 1-2 years to just get your money’s worth.
I don’t have any, but I think they could do with some buffs. That would make them more appealing.
