Rogue is still pretty solid: it has draw, it has fast damage, it has way to make boards.
Warrior has good stuff too, even if not very strong compared to paladin; frenzy warrior is not that bad, it may be better once decks with minions in it will come back thanks to the watchposts nerf.
Shaman: no clue what shaman is supposed to do: elemental has no purpose, murlock maybe has a chance, but why?
