Chests, open now, or wait?
We learned recently that we will have a chance to get a chest inside of a chest, with the new IP reward change. Do we assume that this change doesn't happen until this patch is implemented? If so we shouldn't open our chests and hold on to keys until they add a chance for us to get double loot.
"To offset the disenchant rate changes, we’re going to change the way loot chests work so you’ll have a chance to get two drops in each chest. Get ready for chests inside of your chests."
^ (Change the way chests work) does not specify current or a new chest.
