Creating a distinction based on armor skins still doesn't give any gameplay advantage though, someone with 60 armor and a regular skin is just as protected as someone with 60 armor and an elite skin. Distinction for older players was the goal of the HoM at conception according to their interviews anyways. There's also no telling how any potential HoM-derived armors will look compared to standard GW2 normal or elite armors, and the fact that after any real amount of time the game is most likely going to wind up with anybody able to get the elite armors that want them.
It would actually also be funny if they left it so newer GW2 players could buy GW1 and try to get things for the HoM if they really wanted to. One of the old interviews says that they most likely wouldn't since they wanted to reward older players, but it could be used as a way to try to lure people into purchasing the older games if only to get a set of armor they wanted. I've seen people spend money on stranger things in online games already.
Your armor theory is mine as well, maoric. I've always thought that, given the direction armor took in GW. I remember the original armors had preset bonuses/effects. When they changed that to basically class-based armor-rated skins that players can mod with insignias, I assumed they would keep going in that direction with GW2. --- The unexamined life is not worth living. --Socrates (attributed)
But both ways are annoying, so I don't truly think ANet will do a thing with the HoM. They make some insignificant title, which is definitely less hassle than reskinning armor or making new armor for old elites.
