They don't. Problems is everyone wants to be leader not understanding how long it took us older leaders to get to 10 11 12 clan levels.
At least now you can raise your clan up just by grinding, I had to do quest get items, and to get level I have to be a castle lord for a few months.
Thing that hurt for me was stripping away all my clan skills (took us 3 years to get them all) not many clans had full skills, and cutting my clan size from 160 to 62? (I forget not home now) I mean fine you wanted to do away with the academy that understandable it was pointless as levels rose, but the clan structure was nice, gave people officer positions and they felt like there was an actual power structure in the bigger clans, at my height I had over 100 actives and 30 semi active members rest were alts or mentees. So you can complain about clans but there not as hard to manage as they use to be. Nevermind I was also an alliance leader plenty of times, even when you could have 12 clans in an ally let me tell you what kind of headaches that was, get together 12 lords to make a decision on anything good luck.
