The required synergy of your deck makes regular hearthstone no fun anymore. The cards in your deck have to make perfect sense for it to be viable in standard. If your deck doesn't make sense it is not going to win, ever. I want more freedom in my deck's crazyness. That's why battlegrounds is fun (currently, they are rapidly destroying that). Combinations get crazy and sometimes don't even make sense and you still win. (Seasoned player, I have played Hearthstone since vanilla).
