Depends on the leaders.. they were really fortunate they got all of that mileage out of them
There would be times throughout the year where it seems like they would just be coasting (same with Foe at times.. in F2P anyway) or even fall out of the top 3. Of course it wouldn't last long partially due to Foe declaring full outs on them so many times when it seemed like Mm were slipping - or clans pissing them off (E, EoP, Fi right before EOC) Mm had that extra gear clans just couldn't match
A clan of that size reopening would be great for the community, we've already seen how lame and boring things are when there is only 1 top clan running around crashing everything... with Mm there would almost always be a top 2 or top 3, which hasn't happened in a LONG time
