I agree with the article that the competition and work-ethics in SC2 is lower than in BW, however, I feel like comparing anyone in the SC2 scene with someone like Jaedong and Flash is quite unfair. Jaedong's career is longer than the entire lifetime of SC2 and even then Jaedong has been standing on the shoulders of the giants before him, who have been standing on the shoulders of the giants before them. SC2 is a very young game where nobody has figured everything out yet (it's still being patched ffs).
The article mentions the work ethics of SC2 as compared to BW, and it's clear that BW players train harder. While this means that the competitive level is higher in BW, I actually feel like the competetive environment is a lot healthier in SC2. People should play SC2 because they really want to, not because they absolutely have to in order to be able to compete with the rest. Now if someone simply has no other desire than to train 15 hours every day, 365 days a year then so be it, he's going to be amazing at the game. The reason why Jaedong is so good is (arguably) that he has such an insane practice schedule as he has, he just does it naturally as part of his mind-set and aproach to the game. However, Jaedong practices this much because he wants to and not because he is required to, which I believe is an important distinction. I believe the main reason why BW players practice so many hours is because the current top players are the ones who practice the most, so in order to compete the other players feel like they must practice just as much if not more.
In SC2 this is not true (that I know of) to the same extend. I don't believe MC practices more than HuK does, instead MC is simply better at picking up and mastering a new game faster than HuK is. As long as SC2 continues to be patched and new expansion packs are on the horizon I don't feel like mass gaming will have the same impact on skill-level as it does in BW. Instead the game will reward creativity, adaptability and intelligent play a lot higher and allow players who put in less hours to still out-shine others who play more. In the end I feel like this is a much more healthy aproach to esports than what we know from BW, where nerds can literally not have a social life due to the amount of hours they have to invest into the game. Once SC2:ProtossExpansion settles down and things become more and more figured out I believe we'll start to see mass-gaming becoming a much more important factor to a player's success and BW work-ethics will become prevalent. Until then players will have more freedom to play less, develope social skills and become more likeable, normal persons who have more fun, and isn't that something we all want to see happen?
TL;DR:
The competitive level is higher in BW, but the competitive environment is more healthy in SC2. Mass gaming is less important in SC2 which is why we don't see it as much, but once Blizzard stops patching and releasing new expansion packs things will settle down and mass gaming will become prevalent. Until then players are free to be more relaxed and have FUN with the game, which is a good thing IMO.
Sheesh, that got longer than I expected
