So I have been all over the forums and looked everywhere I could with no luck finding the answer to this. At least, not an answer that is current since Darkshore. How often do the War supply chests drop? Last I knew it was every 20 min. Is it still every 20 min? Is it every 20 min PER zone? Or every 20 min in a random zone? Any confirmation information would help greatly as I am trying to finish off my xmog set from those boxes.
