I think this question mainly goes for people playing the older Horde races. The only things NEs and BEs have to worry about are ears and eyebrows poking out.
Since UD and Orc shoulders have been broken and "fixed" both classes have been (So it seems) slightly shrunken, and therefor the shoulder armor does not rest perfectly on the shoulder, etc.
It just seems like Blizz puts a lot more effort into making Tier sets for some classes (Warlocks) flow seemlessly and meld rather well, while a few others get boned.
Is it prissy and whiney to want my cloak to fall evenly on my back? Bah, sometimes my aesthetics prevent me from enjoying the game the way I should. In the middle of a fight, none of it matters, but when I'm just sitting around in Shatt I am a sad panda.
Also, does anyone know if upped graphics settings help with clipping?
