[quote name='icedrake523']I say why watch someone play a game when you can play a game yourself?[/QUOTE]
While this may be true for some games, I also watch Starcraft 2 pro leagues. Those games are extremely fun to watch. They do stuff that I could never do in my entire life. I'd like to think I learn things from watching pro games, but there's a point where you're just not fast enough to do the things they do in SC2.
There's definitely things to learn in watching pro LoL games, but most of it amounts to very good teamwork or crazy tower dives. I'd much rather watch SC2, but I'll watch some LoL too if there's a high level, high profile tournament going on.
I've tried to watch fighting games, kain, but that's not my cup of tea. From the few games I've seen of MK and SF, it's 20 seconds of blocking, one huge combo, 15 seconds of blocking, and another big combo to finish it off.
