To note: The BOAs AT THE MOMENT are limited to 1-80, but once T11 raids open the two new ones will scale 1-85Also, listed on the BoA collections tab are BOA legs, back in the day those were tied to a Mists of Pandaria guild achievement for 600 skill points in all professions. No idea why BoA legs are showing up in the collections tab... but.... Eh
Just saying that the gold amount you mentioned is wrong.They would cost 2700gold if you could buy them at neutral, which you cant.The cloak costs 1140g on friendly -> 1080g honored -> 1020g revered -> 960g exaltedThe Helm costs 1275g on revered -> 1200g on exaltedTogether 2415g if purchased directly as soon as you unlock them, 2295g on revered and 2160g on exalted.
