I've been wondering why I almost always see the swamp background upon starting the game. Finally found this explanation:


Hmm... in theory there's a higher chance that it'll pick the background from the most recent expansion, but it's not 100% guaranteed: the backgrounds should cycle after a while.

Not sure what "after a while" means. (Months after the expansion comes out? Can't be, since Tempest came out 21 months ago.)


While I'm looking forward to seeing the Inferno background come up, the same thing will happen, years from now, we're all sick of seeing the Inferno background all the time when there are 11 other beautiful ones that could be on rotation. Could it be set to pick from the pool evenly, after a few months since the expansion releases?
