And i would really like to see some of those wierder mechanics at work, i feel they would be very hard to master properly, but i guess that's why LoL is liked by many, it's very easy to learn and play well (don't go derp and you are all set) while Dota requires some more practice, also some aspects of it i don't quite like (denying for one).
Also the lower entry level for LoL means more retards, like in the game i am playing right now.
As someone who played DotA in its prime for a good six years, I'll tell you there's a bit higher skill cap for DotA than League when taking into account the number of things you can do in terms of influencing the early game. Creep pulling, jungling (which is a bit harder than it is in League), denying, creep blocking; they are all small parts of the game that can have a pretty big impact if not done properly.
It doesn't have much of a lower entry level though. There were still just as many retards in DotA as there were in League. More things to do stops no one, and since this is carrying the name of a popular game I have no doubt that it will end up having similar rage/noob/dumbass issues.
