Actually making transmog available through coin shop would overflow the income from Lordaeron without creating any ingame problems with gear,lvl,profesions,materials and other ******ed stuff. Gear should be completely removed from shop, just transmog,mounts,pets and so on,every f2p server nowadays works like that. As for the problem with actually being able to "see" what kind of gear someone is wearing,just inspect or get gearscore addon. Even in arena,ppl are looking at opponents GS and HP, not trying to "see" the actual gear. Its custon, but it would fix a lot of issues. And server will already be customized to a certain degree,just why not to make original retail experience better? Even the new client with HD models is technically a custom feature..
