I have to say that this sort of thing really p..ses me off. There is no reason not to have account wide stuff. For example, a pet peeve of mine with WS was that the mounts weren't account wide. It sort of put me off the game because I had some decent mounts but didn't want to use them because I wasn't sure what char I would be maining.

For me, I am stalled at level 15 odd or something like that because I almost stopped getting XP. I want to complete the map I am on because that's the way I like to play but I get penalized heavily for doing that. It's absurd that I should get penalized for trying to do all of the content. I don't want to create 15 alts to run through the content again and repeat stuff just to do the odd thing that I missed.
