I felt the exact same way op. I’m not really a fan of dungeon content and even less when pugs are involved. That said, after seeing everyone rave about how good it was I couldn’t resist and took the plunge anyway. It was my first dungeon in GW2 and it ended up being pretty darn fun, wiped a couple times(once on trash then again at the final boss) but we got through it well enough. Completely agree with the dev that it was the best way to end F&F.
Just give it a go, whats the worst that could happen?
