350 hours so far, time for a little recommendation.

It's literally dota with better graphics, it works like dota, it plays like dota, it feels like dota.
Valve also hired Icefrog as the lead dev of the game, which is a very good thing. This way, we can expect same quality heroes after all the dota heroes are finished. Of course those'll be stolen by HoN on day one, though, but that's another story.

There is a few cons I have to list, though. For once, being from the EU can be a pain in the ass. We need EU East and EU West servers, mainly to keep the russians away. I'm not trying to be racist or anything, but it's just that, you lose most of the time with russians. This isn't because they're just hurr russian, but because they can't communicate with you. I'm open for any russians that can speak english in a way, and I've seen some before. But others that just come in, die in the first two minutes with 200+ wins on their profile and make you lose the game, that's a joke.
