Clans were made to effectively kill players on rs, it got a little more serious and competitive over the years but the peak of pking was probably 2005(end) to 2006(beginning) the small clans had their rivalries, the big clans had their rivalries and everything was organized by the clan world community not jagex, so yes I do think Jagex killed clans with the removal of the wilderness, adding of the clan chats, and the adding of clan wars and bounty hunter.

I somehow agree with the fact that Jagex' support has killed clans.

However, I think it killed noob clans. You see, all the low level players don't want to be in the tedious business of searching for a clan. They can just join Mod_MMG, or the Zezima hunt chat :P

 

I think this has actually separated the 'noobs' from the experienced clanners.
