I think the moment they seriously try to monetize dota 1, the game will go extinct.
Monkey King is gonna become available to anyone as soon as they are done with testing. It's in beta version now & it's buggy as hell. I guess they could do the testing locally, but you guys already fixed that problem by the psr restoration in the case you get rekt versus it.
I honestly do not see any problems with them charging for the hero skins. Even tho it's not really that interesting to me, I can see it might attract new players here who find those kinds of things cool. There are some pretty nice designs.
