I agree with you on that, but remember there are a ton of low level pures out there who are clanless. Just look at PVP worlds and edge, crabs, experiments etc. Multi clanning is a problem, but it wouldn't be if the LPC/MPC community just doesn't acknowledge the HPC community. I honestly have no plans in joining a HPC because well fuck 20+ defence. Since when was warring 60 v 60 in full mithril fun? Current HPC's with a history (looking at FOE,TLP,FI, etc the pioneers of pure clanning) SHOULD BE ASHAMED OF THEMSELVES.
Props to MM, even though at one point they did allow 20 defence. A majority of their clan was still 1 def.
Whats the point of competing with majority mith when you simply don't have to (current LPC/MPC times).
