I play Dota2, never tried LoL but friends told me it's pretty much the same.
And I usually support
Do you play? If not, why not?
It's free. If you've ever heard of DoTA, it's the same concept with a much lower skill floor but still a relatively high skill cap. (ie, it's beginner friendly but good players still stand out) There's a tutorial mode within the game as well as the ability to play against bots if you wanna test something or try a new champion or even if you're just not comfortable against players.
For those of you who do play... who do you main?
I generally like playing heavy CC/AD off tanky/initiator. Been playing a lot of nautilus, but alistar/blitz/riven are up there too.
