Interesting concept, at this point its clearly a spit ball suggestion. A fairly well thought out spitball but probably needs meta data refinement that only Anet actually has. Kudos to the effort and at having a constructive suggestion that isn't a total gimme. Though I might suggest that instead of getting stuff that's already out there that these "prestige coins" (need a less in ones face name) get you a (few)unique skins. Lots of skins are locked behind specific modes of game play, you need do do fractals to get fractal skins. You need to do wvw (though not much) and PVE to get legendary weapons, Raids to Get legendary armor, etc. If you had veteran sets of armor (not outfit) per type and a set weapons that were achieved through this method that were, um unique enough to warrant the grind and goal to get that level and have those already there something to do this could fly and give some long time players reason to play some of the stuff that was fun but now unrewarding otherwise with newer players. The skins would maybe need to be Black lion level but certainly NOT legendary level art and effects. Almost like those fan made weapons. I thought they were fantastic but easy to obtain. If they required this method to obtain them I'd most definitely have set a goal to obtain them. So ya to summarize, make the purchasable items skins unique to this reward system that are uniquely great but not awesome. The "Guild" in Guild Wars got replaced with "Gear" looooong ago; that's the reality. Also make sure its for vets not elites.
