The issue i have is that i feel that it is a bad thing to have to pay more than normal, to experience an expansions content on my main character. This game prides itself on having a One-in-all kind of gameplay, which is broken by adding races without at least one free change to the new freshness.

If the game was more alt friendly (a la WoW) i'd be fine with it. In those MMO's you are required to play more than one char if you want to experience the full show anyways with the alliance/horde split. In ffxiv there is no such noteworthy split aside from certain NPC's having minor changes in dialoge.
