How would you describe the state of the game right now ?

Hi guys, I haven't played a card game in decades and I'm itching to get back into one. So as someone who has never player hearthstone before, how would you describe the current state of the game ? What's the f2p like (although I am not completely against spending some money if the game is fun) ? Would say the current meta is fun, is the game on a good trajectory ? Overall, are you optimistic for the future of the game or should I just move on and find another game ?
