Why all servers have the same settings?!
Some pleople cant log in 6 hours all days, and getting offline raids all the time.
Many servers wiped by large clans.
Some friends (more than 4) quit the game for above reasons.
You sould wipe some dead servers (with or without poll) and change the server settings. You have the stats now. For example: if 20% of the clans have 2 players, 20% of the servers sould be with max clan size 2 players.
Most players, does not vote in polls. Use the statistics.
Bonus suggestion: There sould be direct (in game) button for player report
