I havent played it in awhile myself... the game gets a little too repetitive at times for my tastes, though it depends on my mood. The "pay 2 whatever" aspect I dont mind, as far as I'm concerned with CCGs you're supposed to pay for card packs to keep playing, that's how it's always been.
The game's overblown randomness can get more than a little irritating at times. While I SORTA understand why they did that, at the same time I still find it kinda derpy. They're already in a genre that's made of random! Anyone that's played, say, Magic, and has had the hilarious experience of being "mana-screwed" knows full damn well that there's already enough randomness. Granted it's not like HS goes so random that it breaks or something, but it'll occaisionally feel like there's not much strategy happening... wether you're winning or not.
Regardless though, since I'm bored out of my mind lately when it comes to competitive games yet cannot always play the competitive games I do have (because of my arm) I'd considered getting back into this... and then I heard about the C'Thun issue. From what I'm told, every deck is C'Thun right now. And really, just... ugh. I know deck types get more than a little repetitive in these, which is boring but typical of this genre, but the situation with this one sounded way overboard. I cant imagine what the hell the devs thought would happen with a card like that though.
I figure maybe I'll wait awhile longer, thusly. Not sure. Hard to decide sometimes.
