One thing I have noticed is the vulching a shade account isn't really being done for rank anymore, which in my opinion stems from those that do it for score being exposed and having their ranks erased by HTC. The new trend seems to be to vulch a shade account to farm perks to use in the LW, which is why you see a lot using fighters to vulch 2nd accounts in a GV. This way, the kills won't count towards their fighter score, potentially exposing these twits and they still get perks for the kills.
