Exactly. I tried to play casual to avoid netdecking tryhards, but after the first game against Murloc Priest (!) I gave up. I personally love deckbuilding, creating a list of my own and then experimenting with it, making changes, seeing its weaknesses and strenghts. That is my favorite way to play online card games. However, now it is impossible in Hearthstone (not only in standard really, wild is the same), since every time I try to actually make some logical plays I get smashed with some unbelievable RNG, Secrets making my cards not matter at all or just generally unfair plays like Druid building a full board on turn 1 or Rogue with a 10 attack weapon on turn 4. Spell Mage and Secret Paladin are just the tip of the iceberg. I love Hearthstone as I have been a part of its community all the way since open beta, but the direction the developers have chosen is slowly reducing fun in playing the game with every year.
How can you put those two things in the same sentence?
