I read this article yesterday, and I like how Riot has related to the DOTA players out there. I agree, LoL is an improvement over DOTA. They took the best of DOTA, and made it better. Only negative I see with LoL is some may feel the graphics are too 'childish'. And I can see there point. I kinda wish the graphics had a more mature look to them, somewhat like HoN. I'm not saying the graphics are bad, they have their own style, it's just not my favorite. None-the-less, they are good, and the gameplay mechanics are amazing.
I also like how LoL isn't a 'copy and paste' job of DOTA, like Heroes of Newerth. I'm glad they put more thought and invention into the game. HoN has no originality about it. They simply took DOTA and basically made the EXACT same game, with updated graphics, and added player stats, etc. To me, this is where LoL excels. They took DOTA, and invented a totally original game, putting more thought into it, and adding so much more. Bravo Riot..... now if you could make the graphics more mature...... haha
