I installed and played Hearthstone specifically so I could win three games and thus get a special mount in WoW. I basically hated every second of it and as soon as I won my third game I bailed and haven't played since.

I don't even know why I hated it so much, I just did. I really wish I liked it because I've been a huge Warcraft lore nerd since forever so I know who all the characters are and get all the references and so on. But I just didn't like it.
