I don't usually post on the forum here, but I was hoping to give my two cents as someone who plays this game on and off. I actually agree that the expansions should take longer. From my experience with TLE (specifically Varsoon is the one that I played), I always felt rushed because my time was limited in experiencing the game. I ended up quitting after an expansion or two because I didn't want to have to keep catching up to everyone speeding through the content.
I think this kind of attitude while playing the game makes people toxic (people are always rushing to the end content and want to finish it first, or in time), and makes it a bit harder for newer (or returning) players like me to have fun. I feel like this also keeps newer players away from the game because they may be unfamiliar with the game, its quests, etc. Some people also like taking it slow, like myself, and many of my friends. Many of us love playing Everquest 2 but feel pressured by the constant expansions and newer content.
My personal opinion would be to have this server continue to RoK then stop there, then have another Time locked Servers based on old mechanics for the older players that like that kind of thing. I feel like having 2 servers like WoW classic, where one is the original (I think RoK or KoS is a good stopping point for this) and the other is a time-locked expansion server for those that want to continue would be nice.
I also wanted to add that I believe that the Krono selling made things worse, although the best solution is good moderation.
Either way, this server sounds exciting, and I can't wait to play it when it comes out
