Weaker turrets, weaker junglers, creep deny, couriers and scroll of teleportations make the game "faster", it has more ganks and more lane changes, not to mention that heroes are more different than each other.
I used to be a DotA hater compared to LoL, but after a few thread like this, my arguments didn't stand anymore. DotA 2 is better as a competitive game, but I'd agree that LoL is more noob friendly.
