I'd love for AL to put out their (hopefully, eventual) BD in broadcast order.
The full chronological order is the way to go now that the second season exists, but season 1 in a vacuum is really fun to watch in its original order.
(The original Japanese BD box of the first season did this, IIRC.)
One the one hand, second season of Aldnoah.Zero for £15 is pretty good, and it'd be nice to have to match the S1 set from the mystery box a couple years ago.
On the other hand, the second season is an absolute trash fire.
