So I decide to try GW1 (bought only prophecies). If I will like this game maybe I will buy Factions/Nightwal and Eye of the North also (and I can get HoM only with EotN if I read FAQ correct?).
My question is: If I do some "achievements" now (without EotN installed) I must do this again for HoM stuff (if I decide buy EotN) or it will be just added automatically when I visit HoM first time?
