As far as I know there is no non-logo'ed version of the Mercury skin. For me it is ok to use that one.
Team XFR should submit their skin as soon as possible.
Im not sure about dRagonality, since they never posted or sent a skin to me. Also since their LFS team doesnt exist anymore, Im not sure if we can still find the skin. I'd say if they happen to see this they can post their skin, if not you can leave it out.
