If you really wann point out what valve did here, just look how many stuff got implemented in dota 2 what has been in HoN as mods for 2 years now, theres plenty.
Sometimes i think the dota devs were looking on dota clones like hon and their mod communties for inspiration.^ ^
woah wait, somebody saw a lamp and invented a lamp shade? holy ****,
That i am seeing is a company giving oppportunitites to mod creators to make everything they want, and they do while the game is evolving....
ofc HON mods are superior but why to do more mods when you get no recognition, no money and no acceptance.. also mods can be seen only from you and not the others...
well , maybe i am wrong but the future ll show us who made the best choises about moba
