Doing "the Insane" achievment on several toons is probably not viable for most people. Heck, for most it isn't viable to do it on even one character. I am all for accountwide achievments, but wouldn't there be issues if that was the case? I.e. everyone rolling humans for diplomacy then workingof all rep factions on just that toon? Diplomacy could be taken out of course, but there are many more issues with this than just the technical ones.
