It seems really long since we had one of this, the last nerf I remembered being for Undertaker if I'm not mistaken. I personally quite like Patron Warrior as I love combo decks but this pretty much spells the end of the deck. I've seen Patron Warrior win by controlling the board with just a lot of Patrons but it will be very susceptible to board clears. I wonder if there will be any adaptation possible to keep Patron Warrior as a deck.
The other effect of the nerf is that we lost a powerful and relatively cheap deck for clearing Warrior quests. Some of the alternatives will be OTK Warrior involving Raging Worgen (http://www.hearthpwn.com/decks/267912-kolentos-otk-warrior-30dmg-in-one-turn) or Ostkaka's new Charge Warrior: Hearthstone Subreddit link
Update: Surrender, a Hearthstone player from Korea, is playing this new version of Patron Warrior as reported by Hearthstone Top decks: http://www.hearthstonetopdecks.com/decks/surrenders-season-19-new-patron-warrior/
Update#2: Xixo with another post-nerf Patron Warrior deck: http://www.hearthstonetopdecks.com/decks/xixos-season-19-new-patron-warrior/, the main changes was no Emperor Thaurissan which I agree as it's less of a combo deck but more midrange now and opting to use 2 Frothing Berseker which is still a powerful card that requires answering immediately when put on board.
