There was a difference in the rules for the professional competition and the preliminary matches.
The preliminary matches differentiated between the home and away teams. The home team could choose the location of the battle. Furthermore, the calculation of the points depended on the number of wins and the points accumulated during the battles.
For example, Quan Zhen Sect had won the first round of the match-up, and thus had five winning points and three match points. Thus, the calculation of the points was relatively complicated.
Therefore, in the professional competition, the organising committee had tweaked the rules slightly.
The right to select the map location would alternate between the two teams. Even though the home team had the right to choose the map in the first round, the away team could do so in the second round, and in the last round, the right would once again be returned back to the home team.
