I had an idea that could possibly help loading time a bit.
/hideaccessories
This command would tell your game client to not display accessories on any PC.
Could possibly set modes where it would display party members only or off while in towns.
I do like the fact that accessories are shown in general, it's just loading so many PCs bogs my machine down quite abit, espicaly in Ul'dah, and reducing the load times by anything would help me out.
