Played dota 2 since it's release last year.
But played dota 1 for about 3 years.

I tend to be given the carry role, as my current friends I play with don't like the pressure. That said I play a support/gank role the best. I also tend to call the shots on when to initiate, go, push, b etc..

Never played HoN or LOL - I consider both to be rubbish :)
as a good friend says it - playing HoN/LOL is the same as playing counter strike without recoil or reloading! skill level, minimal!
