After playing the RPG genre since practically when I was a kid (as early back as the original Legend of Zelda and Final Fantasy 2), I decided I'd like to master a new genre unfamiliar to me, which would be RTS and MOBA.
A lot of my friends have been getting into League of Legends, and I've been interested in picking up Starcraft 2, but the reason for this interest is because of my interest in tower defense games. I'm ok at those at best, but I've never done online gameplay for said genres before either.
What's the best way for a newbie like me to learn RTS and MOBA? I don't think I'll be getting into eSports level competition but would like to at least attain some sort of respectable gameplay.
