Naga priest and bless priest = They dont care what you do, they just do their thing and then pop off, 1 turn to answer or you die.
Relic Demon Hunter = They only care what you do the first 3-4 turns. After that they dont care at all while spamming x amount of mana in the same turn. Killing huge boards, making huge boards and drawing their entire deck that they can play for free.
Aggro Druid and Imp Warlock = They only care about one thing, your face.
Curse Warlock: Can kill you without even hitting your face once. Full of removal, heal and crazy carddraw. Its like playing against a timer.
Mine rogue: Same as above minus the healing.
Ramp Druid: Busy ramping and scamming, casting some huge removals and huge taunts every now and then to keep you away. The biggest interaction you have against them is trying to hit through their big taunts. Again like playing against a timer.
Edwin Rogue: Either you face a gigantic Edwin at a turn where you have to be priest to remove it or you get hit in the face with x20 weapon or you are looking desperatly for a taunt because lots of non interactive ghosts are waiting for kill you.
Quest Priest: The ultimate non interactive deck that only removes, and removes, and removes. Put something down on the board, hope it stick, if it dont, repeat and try again. A few turns there will be a minion there that you can kill. Playing against the timer again.
So whats left then?
Mage, Hunter, Paladin and Warrior.
Warrior doesnt exist but when it does, it some deck that only use cards for gain armor until he drew Grommash and the copy card to otk you. And if enrage ever becomes a thing with future cards it will never be a deck that have to interact , it will go face imp warlock style.
Mage, it semi interacts with you but not really. Its like playing against priest only instead of clear your minions they just freeze them, indefinetly. And if you are lucky to not get frozen a turn then attacking face is reduced to doing 1 damage per hit. And while you where frozen for 5 turns there are problably a lot of minions that you have to kill anyways. Time has also started ticking because chip damage you cannot stop has made your hp low and mordresh and Magister will soon put you to sleep.
Paladin : You trade, you hit back and forth, they kill some of your minions, you kill some of theirs. Sometimes you hit their face, sometimes they hit your face. The way it should be. Sadly paladin is not quite strong enough so its seldom you will meet them.
Shaman: Fun and interactive deck. Until they use Denathrius x 3 with parrots and whatnot. I approve it nonetheless but Denathrius shouldnt be a thing.
Hunter: Also a fun and interactive deck to play against. Sure they can highroll and occasionally sneak out a beast a little too fast but more often than not it doesnt happen. A good deck where the power is spread out during the entire game The cards and turns and powerlevel grows in a healthy manner.
Conclusion:
Half of the decks is just doing their own thing waiting for that 1 big popoff and then you either have 100% the correct cards to answer them or you die. The rest of the decks they just remove everything you put out while at the same time killing you. Solution is as always, play aggro. Its not a problem, just play aggro. Blah blah blah. Not everyone want to play aggro.
If i was lead director for hearthstone there is only 3 decks in the game that would get my approval.
Shaman, Hunter, and Paladin ( and there wouldnt be any Denathrius).
