Naniwa was a one trick pony. He only had to win 3 games to get to the grand final, whereas Leenock had to play through open bracket and dozens of matches. I think he got lucky that Nestea had a couple off games (probably because hes not used to international tournies) and he only beat Huk because PvP is broken. Skill is relatively meaningless in PvP, it is so much to do with luck on build pick that its just stupid. I think MVP was playing bad for him, but still was the best player at the tourney. Leenock won his games well, but I didn't really see anything great specificly about what he did.
I dont like Naniwa's attitude at all, he is not funny in his cockyness like Huk or MC, he is just a nasty little dirtbag. Apparently he said something about Nestea's play being random and stupid, yeah thats why it won him 3 GSLs.
Although I find all the phony friendliness in SC2 boring, I hate even more the blatent disrespect for the game, its fans, other players, and the organizers of the tournaments, that this little a**hole puts out.
