you can copy the idea, you can copy the format, you can copy the layout... but you can't copy RESPECT! you can't copy INNOVATION! you can't copy the FANS!!
the BRAIN that works on Dota2 is the brain that actualized the MOBA/dota genre. it's the brain that took a limited engine (wc3) and created the most popular multiplayer concept in years! THIS is the brain that keeps dota2 running, this is the brain that brings new ideas and innovations to dota2.
in contrast, the horsebrain that's behind LoL are people who failed to successfully develoup dota (mapmakers prior to IceFrog). the brains behind LoL failed to make the genre grow, they had to wait for icefrog to clean up their mess, and then they copied icefrogs new ideas and concepts into LoL.
which of these BRAINS do you think will create the best product and experience long-term? choice is EASY
