I'm just not sure about this. I read that if I play through Steam I have to buy Heavensward through Steam. Does this mean if I bought it on Steam, I'm locked and have to buy the Steam version of Heavensward or if it's just like the PS/PC thing where you have to buy a PS copy to play on PS and a PC copy to play on PC (as in you need the Heavensward Steam version to go with the FFXIV:ARR Steam version) 'cause I heard some people bought the game on Steam but play through the official SE client.
