Has anyone else noticed an increase in the number of GvG packs (as opposed to the other options) being awarded as rewards for your arena runs? Seems like they've upped them now that they're going out of style. Just got my first Piloted Sky Golem and Powermace (and a second Enhance-o Mechano) now that they'll only be good in Wild. Ah, well. Maybe I'll find some use for them in a brawl or something.
I finished a 7-win run the other day that got me 175 gold and a classic pack, and I think the one before that I got a TGT pack, but the one before that was GvG. So no, I haven't really noticed an increase in them, though they should certainly ween them out of arena.
