I think the Anet's goal is (or should be) making every active player want to buy all 3 campagins. That's why the content of neither of them should be considered 'worse' than in another.
What's the point of adding new armor in Tyria (15k Knights) when it's so unattractive and sub-par statwise?
**The Solution**
My idea and solution to all this is to add an NPC somewhere in *Elona* who can take an armor piece *customized to you* and at a small fee (not higher than 1k) clears that piece of all mods it had and turn it "insigniable".
This way you will still need to own Nightfall to take advantage of the Insignia system, but owning older chapters gives you access to tons of cool skins. So it works in both sides - if you don't have Nightfall, you get another reason to buy it, and if you started with Nightfall, you can get Prophecies or Factions to access the skins with no penalty. Brilliant?
. In Cantha and Elona, at least you can choose the armour function, and inscribeable armour is even better. I'm not really prepared to spend more money on new armour for all my characters just for the inscriptions when I've spend loads of money already getting most of them 15k armour. I would however like to be able to add inscriptions to the armour they already have even if I wasn't able to change the armour's function.
