It's cool if you actually understand it then. Judging by twitch chat a lot of people don't.
No really, of course I understand him. Ive played in melee tournamets in the past, that was when melee was starting, won a few (a friend of mine won more than me, and he was the one where I spend with him countless of hours during weekends playing, so i was a big melee fan during the whole GC generation), it was the only competitive game I was mildy good at against others. The way you play at the start of the tournament, for example, is not the same way you play at the end. You usually take more risks, are a bit more playful, etc... If you start winning and going up the tournament, against harder opponents, your play is more methodic, maybe even more boring and safe, because you don't want to lose, and maybe you can even get to the first place and win the price.
I did the same as Leffen wthe two times I won (they were small tournaments at conventions, nothing really that big with super pros like where this people attend), so im not mad at him or anything.
Still, of course i prefer a more entertaining match if im not the one playing against. It's fun to root to the one that entertains you, and I will say is the same as watching any sports match where you are don't have a favourite team.
