I think if other Beast Tribe quests used this feature, it would be really helpful for players who didn't get the chance to do them in 2.x, or new players who missed them since Heavensward came out.
I think it would also provide another way for people who haven't done them to level up 50 to 60 (since I've been doing the Gundu quests to help level my Astro).
What does everyone else think?
