First off, 3-1 is actually jsut 1 game from the max. I'd call it the normal score.
That being said, RC did at least do things in game 2 and 4. In #4, it looked like they'd get back in quite a few times even thought SSW always just barely got out (or stole dragon). If not for SSW's perfect score and we knew they'd win in the end, game 4 was tense for a while.
Even when SSW won, at least it was intertainning to watch. Those team plays were pretty impressive before they had a 15k lead and their stats could make them win every fight.
TSM was cowering in fear until game 3 and game 4 was less close than RC's game 4. Actually, by game 2 RC was at least trying to do things, compared to TSM's cowering in fear, it was a lot more fun to watch.
And for the record, S2 was won by China. It's only been 2 years since Koreans won.
