Players are getting bored anyway?Sadly this game is designed in a way where large clans are required for it to function to meet OTMs slow update roll out.
New raids are introduced every 2 years, and if raids like Gele took 10-20 toons to take down instead of 30-40 it would result in players getting bored quickly. The raids being made easier would mean smaller respawn times, quicker kills, meaning more drops.
The required number of toons for a raid encounter doesn't effect drops or kill rate for most servers, it just determines who can kill it and who can't. It still gets killed on spawn in many places.
