I am pretty new to Hearthstone, started in December. I really like the game so far, not really play ranked and enjoy the adventure modes. I wondered if there was a way to implement a casual mode to the single player mode. The AI plays at such a professional level and even a game where I think I will win, I get crushed in round 5 of the dungeon. If there was an option to maybe have an easier AI, with the expense of not winning a card back is fine. I would just like to be able to experience and see what all the bosses look like and it feels like an impossible task for newer players and people who enjoy the game at a casual level. I like to buy new packs and promos that come up, but if half of the game (single player modes) seem like they are off limits and frustrating. It makes me not wanting to keep logging in every day and keep playing.
In the end, having a casual option and the regular option still keeps the modes intact and eventually would give new players something to work towards without feeling frustrated right off the bat in round 3 or 4.
