LoL has worse community, mainly due to the fact that reporting corrupted it with a side-dish of static meta. Testing new lanes and solo heroes is promoted in DotA because there isnt a "final form" of the setup, and playing something your opponents arent used to play versus is one of the greater advantages you can get. Testing new lanes in LoL is met with "im gonna report you troll" and some players even playing worse because they don't want you to win.

Anything you can get flamed for in DotA (such as feeding, not knowing the heroes etc) you can be flamed for and reported for in LoL, but there are things in LoL that you can get flamed for that you can't in DotA.
