Actually, just as Warcraft allowed for modding which led to Dota, Starcraft 2 supports modding. So that spirit is still alive in some form at Blizzard.
Starcraft 2 came out about 4.5 years ago. Hearthstone and Diablo 3 don't support modding, and all indications show that Heroes of the Storm and Overwatch won't either.
After reading some initial reviews of Diablo 3, I just got Torchlight (1 & 2) instead, and haven't really missed D3. They are not a AAA games, but they do have an active modding community.
