More Zadnor instances please.

It's too crowded in Zadnor. FATEs end much too quickly for credit to be earned. I exited and re-entered several times, and it was always far too crowded. To the greatest extent reasonably possible, the algorithm should consider rank when deciding who goes to which instance and whether a new one should be opened. Even if an instance is only half full, if too many people need the same FATE area for decent mettle, it can be too crowded.

(I put this in the "dungeons" category because it's an instanced area.)

Only 72 Players can be in any given instance of Zadnor. It will never be higher, make sure you get 25 Clusters to get the riding map. That way you have max mount speed and can catch up to the train when it's running from Fate to Fate. Zadnor z3 Fates are all next to each other in a tight circle, if you have progressed enough, I think Mettle Lv.22 You will have access to Zone 3 via the Save the Queen Story, and you'll have no issue.

If you are farming mettle, the Fates are not the way to go as they give extraordinarily little. You'll want to farm Critical Engagements or the large Raids that will give you at least a level and a half of mettle each time.
