It would be really cool/nice if we could choose to start a fresh arena ranking with a new or different deck than we have used in the past. I would love to see how different decks measure up in rankings against each other. Right now, all decks apply to the same ranking no matter what. So if I build a new deck (after testing it in play), I have to start in rankings right where my best deck is at. That takes away from several strategies and does not allow me to compare contrast decks and their proficiency etc, nor does it allow me to test and build the deck further in arena ranking style play. I realize the algorithm for rankings is based on number of wins in some ways, but why couldn’t we just choose to start over in rankings with specific decks (while remaining at the rank we were with previous decks)? That would be awesome
