First a quote from the clan guide:
A clan is a group of players who have teamed on a more or less permament basis.
I think a clan should be more then 1 person. How else can you be a group if you are on your own?
As a group of characters with some ideas/thoughs: like killing evil/good, race-based (see dark-elves), or class based (barbs) or search for more knowledge.
But I think a clan should show his thoughts to the outer world. Let others know why you are clanned. By story on bb or by telling/showing others.
I think being in a clan shouldn't make a character more powerfull. Alltough I think, if a clan rp's good, the clan by those in the clan who extually do clanRP (mostly all of them) should get an clan RP item. And after that, a clan could get their own place. Like lionhearts/dark order have now.
The ranking system of the clans should be adjusted too. Now you only get points when you kill another clanned player. It might be from the ealier build of los, but i don't think (clan) players should be pushed towards killing other clan players. A clan should only get points for kiling a clan-player when they are in war with that clan. If not, no reward, no xp, no weapon drop.
This way more clan player will come, since now i notice people being affraid for joining/killing a clan, cause of the loss of xp and % when they get killed. More players might result in more clan-RP, which is an important thing for LoS (RPing).
perhaps more comes up in my mind, but don't want to write more, since stupid pc frooze for quite some sec, leading to a dlvl. (yeah yeah.. should have put lagflee on.. but forgot turning it on after grouping)
