I would like to see some form of an adjustment to the divisions. Nothing is worse than having new or poor players face off in bronze and silver against someone with a dozen or more battle ribbons from the diamond rank. The only thing this accomplishes is the newer guys getting slaughtered and free points for the big dogs.
Maybe make Bronze 20 down to 1 and then go to silver (2 wins per rank til 10 then 3 per til 0)
then Silver from 20 down to 1 and go to gold (3 wins per rank down to 10 then 4 per down to 1)
Gold from 20 down to 1 then making it to diamond (4 wins per for whole division)
Diamond 10 down to 1 to get to S rank. (diamond 5 wins per down to S rank)
Also make it so people cannot battle people more than 5 numerical ranks lower than their own division. For example a gold player could battle someone in silver who was rank 5 through 1 (people close to getting to the next division).
This would also separate the players who are the real cream of the crop, guys with S rank would really have some bragging rights.
