And for the lewd block go to B-069! ;D
Why that block in particular?
I think this is the best block because its in the goldilocks zone. It is active with responsive people but not too crowded that people talk over one another. The people there aren't trolly and they are willing to help new players out. Overall a very good base to build a community.
Which is why I believe this is a great block for new players to fully enjoy PSO2 and the better parts of the community.
They are currently hosting a fashion contest on B-025. Franca's Cafe.
I can assure any non-believer that Ship-02 is the best ship.
