you argue that the economy in cs makes the game impure? what? its another element of the game to strategize and compete in, it adds another dimension. it in no way detracts from kennys' awping that he cant do it every round, if anything it elevates it
you say "soccer is like this. soccer is good. therefore esports should be like this." which is a terrible argument. guess what every ultra popular sport has that tf2 lacks? a ball. more than a ball, it represents a fundamental asymmetry to the game, one side is trying to do something and the other side is looking to gum it up. the team with the ball wants to get it through the net, or past the keeper, and the other side wants to swat it into the nosebleeds.
when michael jordan is facing up against gary payton they both have completely different objectives, theyre playing different roles. when two scouts are chipping away at each other on the flank they both have the same goal: try to get an advantage. theres a disincentive to creating a fight, because the potential of being picked makes it too risky. this causes tf2 to stalemate -- a lot if two teams are evenly matched.
you also complain that an lol match can be won in the pick/ban stage, which is a misrepresentation of what those casters are saying. they SAY they won in the pick/ban, but what they MEAN is that one team was able to play to their champions strengths and minimize their weaknesses better. a lot of times one side will be more geared to early picks, or midgame etc. and so they'll attempt to leverage that advantage into early picks, there is pressure on them to create conflict, to realize their advantage, and if they fail to then the announcers will say aptly that it was a mistake to pick gankers, and the game mightve been lost in the pick/ban.
im not saying that tf2 needs to be asymmetric either, there are many sports which are symmetric, they just aren't terribly popular outside of lone hyped events based more on storyline than the sport itself (thrilla in manila, phelps in the olympics, lance armstrong etc). theyre still a lot of fun to play and improve at, its just the more straightforward, the more "pure" the competition is the less exciting, less diverse, and thus less popular it is.
