Do I miss Zeal? Yes.
Do I wish I could relive my memories of raiding Jbird's group of friends, of ransacking MeganPerk's fortress of traps, of long sessions mining through tunnels and caves to find a long-abandoned underground bunker full of chests filled with diamonds and gold ingots? Yes.
Do I wish I could satisfy my nostalgia? Yes.
Am I going to let that get in the way of enjoying Dragongarde? Absolutely not.
As Kainzo said, the first map you play on is always the best because that's when you develop your first memories of the server. I can guarantee that, after the next wipe, dozens of people will cry about wanting to go back to Dragongarde. But, the show must go on.
Do not dwell on the past - act in the present.
