What $20 difference? I'm saying there isn't a Collection option at all for Steam. Anet decided to put GW2 on steam knowing they take a cut. Their decision, which will definitely be a profitable one with more players coming into the game. So why not offer the same packages for the expansions? So what if you make 30% less? Better to make 30% less than make 0 by not even offering Collection, which is basically all the expansions for one price.
