I don't disagree with valve's action for making an exact match of wc3 dota. HoN and LoL didn't deliever that much because of the changes they made were too much and these changes were dota's core. Of course dota needs a graphical upgrade, but HoN and LoL made it overly eyecandy and pretty in the wrong way. Much of the competitive groups of Dota bashes on HoN and LoL because they took away the elements that was suppsoed to be dota. If icefrog and valve made a complete remake of Dota, they would be able to migrate the huge playerbase of wc3 dota to their game. Lol and Hon downsized the competitivesness overall like no deny and ally's hero status on screen for the less competitive. These changes were really disliked or marked as lazy or people with no awareness in leagues.
Icefrog actually takes the community ideas in full consideration and bug fix response of 2-3 days of map releases. With him supporting, I'm pretty sure valve dota will be able to increase it's playerbase to the less competitive after the initial remake.
From what I read from that article, this game seems mostly runned by the community, like dota is
ACTUALLY, it's just LoL that fucked up. HoN has Denys and I find it actually more fun then WC3 Dota, it's Faster and more intense, has reconnection after DC HoN > Dota in many factors. But I'm really looking forward to the continuation of WC3 Dota on Valves Source Engine because it will add all the bells and whistles that HoN already has, to an old but awesome game.
