I've posted this bs before so I apologize in advance.
Option 1 - Move group size back to 10 permanently. More inclusion, more spots for crap pre-legend classes such as shaman, mages, druids, thieves, etc. Would also give smaller clans a better shot at winning end-game material.
Option 2 - Move group size back to 10 temporarily. Adjust back to 8 at a pre-determined point (6-8 weeks). This option would be considered if Imms think 10 stacked legends are too "game breaking." This would allow inclusion when mud numbers are at its highest and then phase back to 8 when numbers are less and true-addicts are still around.
Option 3 - Move group size back to 10 permanently with the requirement that 2 group members must be non-legend. I made a post months ago about this, but think this would entice people to keep making alts (to fill the non-legend slots), give a strategy portion of compiling your best 10 man for end-game material, allow for 10 at rush (because all would be non-legend) for more inclusion, etc.
