To your point. It should be noted that while Miracle rogue currently seems to be the most powerful deck in the current meta, it's not nearly as straight forward to play as some of the other decks. In miracle rogue you are often left with multiple options for a situation which as you probably know can be the decisions that win or lose you the game. With most other decks the options are usually straight forward with some occasions of having to make a decision between greed and a safe play.
Anyways, I just wanted to put that out there that just because Miracle rogue is the FotM does not mean it's easy to play.
Also, in the lower ranks I've seen people trying to run Miracle Rogue without leeroy. That might net you some wins here and there but without him the deck is so much weaker.
