This is not so much a serious request, as I don't know if it would be good or bad really. But it would be an interresting discussion.
What would you think of a fresh server, where you would have to start over, with content added over time?
Maybe doesn't make that much sense to add content over time for GW2, as there is no treadmill, but it would maybe be fun to experience the vanilla game again (keeping QoL would probably be a good idea).
Then there's the question of cosmetics. If this would happen I think it would be more interresting if no one had thousand of legendaries, and the dream .. Everything would only be unlockable through gameplay, maybe with a battlepass/subsciption. But first of all, yes never going to happen, second of all, never going to happen with an already shrinking community that would now be split up.. Again, I just thought it would be a fun discussion to see what people would think about this .
There is also the possibility of seasonal servers. Mosly a thing in ARPG's, but I believe Black Desert have also done this recently.
I think hitting the reset button in an old game can be very fun. Everyone is at the same footing, and you get that "race to lvl cap" again. And there are usually seasonal cosmetic rewards you can earn, look at path of exile etc. The majority of the playerbase is only playing seasonal, but again that game is more suited for it, with the massive skill tree and tons of skill gems. Rerolling builds in GW2 is not really a thing since you can do every build on 1 class.
What do you think, interresting or worst suggestion in the history of mankind?
