That's because variety is what DotA is completely based on.
It's not the case with LoL.

The absolute number of people following the DotA2 Competitive scene is smaller in total, but larger as a %age of the playerbase.
The DotA2 competitive scene itself is MUCH MUCH larger than LoLs. It's kind of incredible how wrong you are.
EDIT: Let me elaborate. DotA2 IS DotA. Saying the game is new or has a small competitive scene is completely idiotic. DotA2's competitive scene is the competitive scene from a game that predates LoL by almost 5 years.
The DotA metagame and by extension the DotA2 metagame (because they're the same **** game), got past a single viable lane setup a LONG **** time ago. The only way you upvote that steaming pile of **** post is if you actually know nothing about the two games.
