I think MOBA games (except for the kiddie ones like LoL) are popular there because they like their games to be challenging. Most games today are rich in graphics but poor in gameplay, dumbed down for the masses to enjoy. At least in D2 and HoN even the most dedicated players still get a thrill out of sharpening their skills and being better then the other guy.
