It is pretty easy to cut all things about maths that i posted and sentence that TL2 is better even if end-game is completly unknow to all of you. You can't just compare the "rewarding" system of two games considering D3 inferno after 600 hours and more of gameplay and TL2, for just the levelling part.It's just fanboyism. Come on.
The math doesnt matter. TL2 has a far better and rewarding item system than D3 does at the moment. Heck the entire game is just more fun. D3 was fun at first until I figured out what it really was come inferno.
D3 has been slowly moving in a better direction, Blizz is very good at that but the itemization in D3 is nothing compared to TL2 and right now TL2 has far more to offer.
