You can't possibly judge DotA by public games, its certainly up there with SC:BW and CS 1.6 as one of the best competitive games ever made, all for their respective genres. WC3 and HoN are great games, but quite clearly inferior to their counterparts (SC and DotA).
Oh, and don't be acting like HoN/DotA are in any way similar to RTS games. If you're going to argue that APM is the most important aspect of a competitive game then you'd be better off slandering FPS.
