Noted, Blue is Elvish.
And I stated before that Purple has been associated with Royalty, dully noted, IN ACTUAL HISTORY NOT IN MIDDLE EARTH.
I dont see where your issue is against the Eregion Smith swap for the Elven Nobles. They look a hellofalot more majestic and noble than the current models.
And we're in the THIRD AGE not the FIRST AGE, so that argument is without merit. And The Nobles should be more in tune with the rest of the army because as you can see, all the Nobles, such as Elrond and Haldir, were dressed in the same Armour as their Army. The Elven Army is that of Harmony and Perfection, the current warriors of mithlond and elven nobles, apart from the shields, do not fit in with the rest of the Design.
