Invasions easier when less pirates present?

[Basil Dreadflint]

Just a note:

Ever since the introduction of the invasions, DxD has stopped keeping track of Enemies Defeated or Times in Jail!

These are the only two categories of tracking that have been affected by the invasions, but both of them stopped updating as of the morning that the invasions were released to open.

All other DxD categories seem to be keeping updated daily.
