HL3 would have brought attention for sure but you are selling dota a bit short here. Personally I bought in day 1 to artifact based solely on how much I love dota. I have spent hundreds on dota cosmetics, battle passes, etc. Artifact failed because the game just was not fun to play at all. If the pricing scheme was the issue people still would pay money for a game they can't get enough of.

Might be because valve didn't invent dota, it was a warcraft 3 custom game that they basically ported. Game design might not be in their blood.
