Never touched WoW. I'm more to Japanese art style. I play very few MMORPGs. The ones that I've played (excluding SL) are; Ragnarok Online, Cabal, and Last Chaos.
The clan level is from Ragnarok Online, but instead of players donating their exp (which sitters could easily gain tons), I thought about the clan gaining exp every time a member levels up. As for the clan reputation, it's my solution for Rare's "Realism of indicators". He wanted something, but come up with the right solution. In-game achievements is just something I experienced from playing console games.
