Why do people still need to justify to some random troll the value of alts?
Alts are a thing, deal with it, if you don't like them just don't make one, but stop going against people who make them (as per game possibilities).

You also can play the whole game with just one mount, they all have the same function anymore, the rest is just fluff so why collect more, right? They should just force people to play with only one mount.
