I, like many of you have always been fond of playing blue control decks. Many of us that started way back, for me it was Revised, tend to gravitate toward blue. With that being said I don't blame WotC for not making any changes. The fact is Modern is thriving, so why change anything? Blue is currently so bad that 1 unban isn't going to turn it around. My guess is they are fine with how the format is currently playing and nothing will change in April either.
