Finished categorizing all the decks, I'll be updating the statistics in a minute.

EDIT: stats done & up, actually pretty good deck variety, unless you look at Rogue.

Got everything that's up right now categorized.

I generally consider Mid Druid to run 1x Combo and Combo Druid to run 2x

I'm going through and seeing which archetype the decks tend to fall into. In case anyone's interested here's the ones I've done so far. It's a pain just to look at each one and categorize them, so thanks to Flux for actually putting them in the deckbuilder holy shit that's a lot of work.

Most common deck for each class

Druid: Combo (10/16)
Hunter: Hybrid (8/16)
Mage: Freeze (8/16)
Paladin: Midrange (10/16)
Priest: Circle (11/15)
Rogue: Oil (15/15)
Shaman: Mech (7/16)
Warlock: Zoo (8/16)
Warrior: Grim Patron (9/15)
