I think it makes perfect sense to reward legacy players with some perks simply because SE shut down the servers and they lost the characters they'd put so much time into... except that legacy players are getting their characters back with all loot, levels, etc..
As far as I can tell, the right thing to do is to give legacy players the retail game "for free" since they already bought it, let them keep their characters, and some sort of visible badge of elitism. Anything beyond that seems like a bit of an insult to players who either chose not to reward a terrible product or were waiting for the console release.
That said, only perk they can give legacies that actually harms the game is allowing them to keep established characters, because of the potential to ruin the economy for the new playerd. The rest is essentially fluff as far as I am concerned. If a legacy pays less than I do for the subscription or has a kewl chocobo it really doesn't make the game any better or worse for me.
As far as legacy and other players getting along, it just depends on the players. Envy and elitism are not fate, they are personal choices. We can choose to judge others by the way they act, and not just some label.
