In our GNW saturday our group had all 6 battlefields against our opponent group. We also have two of the lowest participating groups with ours usually having around 5-7 people and the opponent group usually only having around 3.
Meanwhile the two top groups on the server who usually can fill every battlefield with three people only had three battlefields.

If this is determined based on the number of participants, shouldn't it be the complete opposite? Fewer people fewer fields?
