We have a limited broadband data and I would like to ask if it is possible to update by parts or something of the sort?
I just purchased the game today (Heroic Edition) and i think i might need to update the client by at least 15GB.
thanks.
As explained, the download will resume at the point where you stopped. None of that “start all over again” stuff with us. 
Of course, you’ll need to download in full to play, but you can stagger that over time, if you wish. (And remember, some of the downloading happens when you enter an area and not in the initial install.)
