Just jumped on the MOBA bandwagon this year to see what all the hub-bub was about! Anyway I probably played way too much League of Legends when I started, went from lvl1-30 in like a month, pretty bad considering my freelance artist deadlines/workload. >_>''
I actually don't play any of these characters extensively but I liked the variety of their design and some are kinda iconic to the game, I also really wanted to use Jarvan's Ult for the lava effect.
My mains are Riven, Volibear, Tristana, Lee Sin and Nidalee :]
I've seen too much people yelling that "DOTA 2 is better!" and bla blah... But I don't see anybody having fun drawing DOTA 2 or making such awesome arts like this one. In a personal opinion, the creativity on LoL champions' design gives more freedom to an artist to create your own environment and concepts on making an illustration. I'm amused. Awesomeness in max gauge.
