Yeah. RTS games are simply way too difficult to learn compared to MOBAs. You have to learn an entire race and at the very least a few basic build orders while you're developing this massive amount of muscle memory for macroing to keep your worker count high and your money low.

Something like LoL, on the other hand, makes it pretty easy to pick up and just learn one champion, one lane, one build order and be an effective team member. It's like the difference between learning to be an offensive tackle vs learning to be head coach, offensive coordinator, and defensive coordinator all in one person.
