Haha, Midrange Hunter is totally real.
I'm only 305 wins from Gold Paladin.
...325 from Warrior. Etc.
I haven't actually played a ton of Hunter the last few seasons, but it was the only class I could play competitively for such a long time (even MR Hunter deck is low budget) that my win total was so much higher. It'll take a long time to get another class there IMO, simply because I've just been switching decks and classes so often the last few seasons that I don't get many snowballing wins with any of them. Like I have Paladin, Mage, Druid, Warrior, and Warlock all around 170-195 wins.
