That's only true if you assume that the zoning is equally important and equally difficult to do in each game. It's not, really. The ganks being easier means you don't need to play as aggressively early for ganks to work, and kill denying means that you can remain competitive in CS while in lane while playing more defensively.
Like to me it just feels like a focus shift rather than adding to the package. You can't really say that DotA is a less aggressive game because ganks are easier so there is more aggression somewhere, but I feel the laners that aren't ganking need to be more aggro in League. Which basically just amounts to laning is more fun in DotA as mid cause you can go have fun ganking with impunity, but less everywhere else.
Also they're far from the same game beyond laning-- mostly in that there's less focus on carries, but that's a different thing entirely.
