I started playing again after not playing for months, back when patron warrior was a thing. It seems like the game is currently at its worst state yet, just everything is cancer, secret/murloc paladins and face shamans galore, then all the other aggro decks that are being run now like the druid one. Atleast patron took a little bit of skill to play, these new decks are completely braindead. Game is a fucking mess and I no longer expect Blizzard to ever be able to balance it. It has to be the worst competitive game out there right now, unless there's something really broken that I've missed.
Grim Patron kept these decks in line. Secret Paladin was below Grim Patron in power level.
With Grim Patron gone, Secret Paladin and Combo Druid are supreme because they are really the only two decks with something broken involved with them (Secret Pally has Dr.6 and Druid has the combo which has been made more consistent with something like Darnassus). Only real way to combat these decks is to play even more aggressive. That means Zoo, Tempo Mage (on Ladder people are playing Leper Gnomes and Knife Juggler in their Tempo Mage and at that point it's basically aggro Mage), Aggro Shaman, Aggro Druid to finish the game before the bombs are dropped.
The hilarious part out of all is that the aggro/tempo power level has gotten so high that Hunter is mediocre now. It can't out face a Face Shaman and it can't out Midrange a Midrange Paladin.
Control decks are really eating shit at the moment. Hardly anyone plays CW as both Paladin and Druid take a dump on it as does Renolock. Freeze Mage isn't being played because Druid takes a crap on it. Priest loses to Renolock, has trouble against Secret Paladin, loses badly to Murloc Paladin and doesn't do that well against Druid either to be honest. Renolock loses to Druid, Paladin with Equalities or Anyfin and even Aggro Shaman... yet is probably the most consistent control deck that is playable at the moment because it just stuffs the deck with so much heal/board clears and Reno Jackson to make a comeback with. So basically if you want to counter this meta you have to play Grim Patron and Oil Rogue. Grim Patron deck sounds good on paper but when Secret Paladin curves out or when Druid draws the nuts you still can't do shit.. and Grim Patron will lose if it goes up against a control deck if anyone is still playing it. Oil Rogue does well against Paladin, OK against Druid but not so well against Aggro Shaman so you are going to struggle with that deck too.
TLDR there's no point not to play Secret Paladin at the moment, maybe you can play Druid but you should play Secret Paladin anyway. Everyone needs to play the deck so the balance process gets sped up. I did my part by going from rank 11 to rank 5 in a day off of a 10 game win streak using Secret Paladin.
