Hon to me seems like a crappy version of dota that was made so it can be seperate from warcraft. I played a total of 2 games on hon and in my opinion; the graphics weren't better just different, its pretty laggy for meanyways, the names are all different so for people like me who have become comfortable with dota don't feel like remember all these new names. The talking systems pretty nice though since you wont have to do vent stuff like switching channel or server to talk to the team (I met this funny kid on my second game named "bag" funny person to hear).
I see potential in Hon becoming better but for now I think dota is better.
