Dota actually has a turning animation.
Juking is much better/skillful, not that running into that silly long grass stuff.
I don't know what you mean by most people don't know of, people who have never played dota or have? Anyone who has played a good few games of Dota will realise items aren't all just all passive stuff or very weak use abilities, they actually are complete fight changers, skills do a lot more, trees can be destroyed etc. There are so many small differences that have huge effects it would be hard to list them all.
