I see the opposite. They are starting to look more like people and less like plastic dolls. If you are comparing this to WoW's character upgrade, well the majority of the upgrades clearly added "character" but it was not at all in line with what they were. Goblins and Worgens literally had character removed. They removed blemishes and any sense of wildness.
The pictures they showed are very much the same, just with more detail, to state it simply.
Please elaborate.
That said, if they really are committed to accommodating a broad range of systems they should have the option to use the older versions.
