Or at least find a way to increase player participation in the 3's bracket besides offering cosmetic rewards that less than 1% of the player base will ever earn?
Maybe Blizzard could give titles similar to the ones earned in Rated Battle Grounds (scout, grunt, sergeant etc.) for every 100 rating over 1500 in 3's, and 5's?
I personally do enjoy 3's, and even 5's, but I don't understand the idea of balancing the game around a bracket the majority of players never even participate in.
