I though about it, but i think that the T11 helmet looks weird in most races IMHO, and i think the shoulders are harder to combine with most gear color wise, but regardless... my main reason to go with those shoulders, was because of the electricity effect that the shoulders had, that's all :P
Then the rest was done based around the shoulders
Note: Also... am i the only one who think that the T11 is based around the Ethereals? (I kind of feel that they wanted to go with a Genie type of design, but i can only see my transmog vendors trying to scam me when i see the helmet)
