A 5v5 confrontation is absolutely not the same thing as a 100v100 battle. Although pro players were admittedly very skilled, much better than the average player, they only had the background of a pro. On the other hand, Ye Xiu's year and a half of madness in the online game, frequently fighting and stealing bosses had greatly increased his skill level in this aspect, revealing a great disparity.
Pro players admittedly had a higher level of tactical understanding, but but on this kind of stage, they weren't necessarily better than the club guild leaders at maintaining balance and control. In situations like these, pro players relied more on their overwhelming ability in order to stop their opponents from seeing their plans to fruition, and using their skill to directly tear their enemies apart. Except now, hidden within the opponent's army was an individual of unparalleled skill in online battles: Ye Xiu. This gap was one that they had no way of closing at the moment.
Unrelated to TKA, butttt I love watching Melee and Smash Summit 6 was easily one of my favorite tournaments ever. It's been a great day for Marths and M2K fans! The return of the king :)
