Dota has many times the depth and strategy of League, along with many more stats and intricacies. League actually just took everything from Dota and simplified it down to it's basic elements, it makes for a great casual game that anyone can get in to, but if you want any form of depth, strategy, or creativity, it falls short. For instance, there's dozens of strategies to play Dota, and the "meta" changes like every 2 months. League seems to be obsessed with keeping it's meta the way it is, even punishing players for playing outside of it. So yeah, I like Dota 2. I can't say anything about HoN or other ARTS games though because I haven't played them.
