What I am Reffering to is, lets take for example now, I was about to lvl up to 35 to go Lion's Arch. It required some criteria to be met. which was either lvl up to 35 (was 32 at the time) or lets say buy an expansion. These types of unlocks I am talking about. Sorry if I cant explain myself so clearly. English is not my first language.
In summary. will I unlock the basic features of the game if I buy an expansion that is yet to be released ?
