There is full body so why the lack of joints, it is a little strange to see the detail and depth bump maps add next to the joint which in comparison seems a little lackluster

Hmmm, joint textures are a bit of an odd one for it since they work more like tattoos than textures. That said, it is pretty odd that they're the only ones without bumps.
If they did happen really some 256 & 512 bumps should be added too. The 128s just don't match up well enough with higher res textures.
Server load? You mean ingame? Nothing really, just longer custom download times & it'd use more storage space.
There would be a client performance hit ingame though, mostly for people with potato GPUs.
