Definitely agree with you both - the writing, and not Quinn himself, left a lot to be desired in his return. While it was nice to have it more integrated into the story than some isolated alert, it's still sad that what by all accounts seems like a final nod at what might be the player's marriage is so lacking.
Having finished all class stories I started wondering if I'd enjoy getting into group content or not. Now I'm starting to think I should just enjoy the story content best I can, and move on when it stops being fun. I strongly relate to you on sticking around beyond all hope Luna, but I went through it all too recently when my greatest MMO love, after years of promises and patience, closed down, made needless changes mostly for the worse and rebooted into a generic F2P I just didn't find the little things that made me fall in love in the first place in anymore.
It's bumbling on like an unloveable zombie now. In its boxers. With the keys to the handcuffs.
Time will tell if I learned anything from that experience.
