Yep, most triple-A releases these days have less polish and less content on launch than this game currently has. Though they obviously have more things in the works that they'd rather roll out during beta than have them as post-release updates, which is great for any of us that are in it.
I'm just curious as to how well it's going to do when everybody can play it. Not expecting it to top League or Dota, but the current average twitch viewership of around 3000 is something I've always considered to be ridiculously low, given how good I think this game is to spectate (much more fun and easier to watch than other Mobas)
