is swapping items a client limitation? I can just hotkey or click on a wep and it automatically swaps (not including 2h w/ an offhand/shield equipped which makes sense) but I can't do that with any other equipment slot. Which for something like rings, again makes sense because you have more than one. I'm not a coder or programmer so I have no idea how hard that would be to do.

most if it is a client limitation.
