All of them are coming out with big updates at the moment. I haven't played HON in ages. I recently gave LOL a shot. It's pretty easy and there are many breasts in your face all the time. Still, I find that Dota2 is far superior in many, many aspects.
It's good to see a lot of updates coming out from Dota/Lol/Hon. Can only mean more content for the customer.
I'm getting a bit annoyed at the sluggishness compared to DOTA 2
I think Dota2 has built in lag. Which is good and bad. I don't actually notice any sluggishness in the game and think it plays really fast and strong. I find Lol really sluggish though. The action seems a lot slower and less frequent that it does in Dota. Could be the skill brackets though?
