sorry bro, I didn't realize you'd posted here!
2.0 is pretty good. they've overhauled the matchmaking, and it's WAY better now.
The store is cosmetic only. skins, sounds, icons, etc. and you can earn coins by playing matchmaking games. so far it's good. I was skeptical at first, but a lot of the changes are sweet ass.
I do mostly play no stats games, as I usually play with some of my clan members, mostly my brothers, and they SUCK. so it works better that way. I started playing no stats recently, as before my bros got it, I was a 1.4/1 kdr. now look
I used to be a 1650psr! I'm out of practice though, and I have been sucking pretty hard recently. My wife hates video games, and i'm whipped.
as for buying it? if you like the genre, i'd say for sure. A lot of the changes they've made put it miles ahead of dota. And with dota 2 being a direct clone, i'm not convinced it'll be better. It might have a larger player base, but that means jack to me. I don't see hon going anywhere anytime soon. there's always 20+ plus online, so it has a healthy player base.
so buy it. and let me know your account. You can join the men with the Giant balls. We're about 50ish. not a bad clanner. mostly guys who play for fun, and don't take it to seriously, though some of us are really quite good.
