I miss wishlists of CTProfiles, they hint at coming out with a version 2, but who knows when/if they will have the time, it was a really nice tool. So far I can only think of 4 different sites that have character profiles, but none of them have the ability to create custom setups or wishlists yet.

Technically any of them could be used to create wishlists by tinkering with the LUA files they use to update, but that would be a lot of work, and as far as I know none of them have anything in the works for better profiles.
