This will be the final report for Ashes of Outland. The recent balance changes made a significant impact on the meta. By the time the new expansion comes, the meta may still not be solved.
Hunter: Hunter is the new king of the meta. Its three archetypes all have strong winrates. Highlander Hunter appears to be the strongest deck now.
Druid: When the nerfs were announced, many believed that the nerf to Fungal Fortunes was insignificant. However, Druid was actually the most affected class by the nerfs. Now it may be the worst class.
Priest: Due to increased meta hostility, Priest became worse even though it received no nerfs. The Cube Priest became worse as a result of the decline in Warrior and Demon Hunter. This makes the original thief build better.
Warrior: The class fell outside of legend, but in legend the class is improving. It will likely return in the future. When Demon Hunter rises, Warrior should improve even more. Galakrond and Kronx have returned in Bomb Warrior to help end the game. Pirate Warrior is vanishing.
Demon Hunter: After five sets of balance changes, Demon Hunter has finally taken a significant hit. Once a new build for Aggro Demon Hunter is optimized, it is expected to return as a tier 1 deck.
Rogue: The class became much weaker in slower matchups. Highlander Rogue was most affected by the changes.
Warlock: Warlock delights at the results of the balance changes. Quest Warlock looks to be a strong deck. Other forms of Warlock like Zoo and Galakrond Control have made a comeback.
Mage: Mage is still good against many of the top decks. Transfer Student is an excellent card for the deck and should be run over Acidic Swamp Ooze.
Paladin: With the decline in Demon Hunter and Warrior, the light has returned! Murloc Paladin crushes the unrefined decks and is expected to continue being competitive as the meta is refined. Pure Paladin has a promising matchup spread and is now better than ever.
Shaman: Shaman seems to be back. Galakrond Shaman sees the most play, but it appears to be inferior to Totem Shaman. Totem Shaman is now a tier 2 deck.
With so much of the meta changed, I think we should alter how we look at some of the new cards. Paladin and Shaman are certainly not as weak as they once were.
