Indeed I do play HoTS. At present I have logged 1,914 games and love this game. I started in late Alpha and haven't been able to put it down.
Well actually that is not true, I was invited to the Alpha and played 4 minutes of the tutorial and then stopped (I didn't know about MOBA's and thought it was another RTS which I didn't need in my life at the time). A few months later (Beta) my buddy asked me if I had played it and knew that my PVP addiction in WoW might be satiated by this new HoTS game. So he drug me back into it and that's when the love affair began.
I have 1 main account with is not F2P but the game most certainly can be. I also have a smurf account that I use occassionally for practice outside of my MMR. It has a healthy rotation of F2P heroes and now days there are quite a few Heroes that are cheap to buy with in game currency.
As far as Heroes that I play, I own all of them on my main account, but specialize with assasins.
And as far as Tournies or Events as many of them as I can attend I will be there. I am entertaining the idea of starting a Chair League team some time soon and will probably post on here to get support or members.
Thank you for the warm welcome and if I see you in the Nexus, we should team up and I can try to show you around. The game is a solid game so I recommend that if it's taking up HD space you may want to take it for another spin.
