Yu think like jagex, well jagex thought the same as yu and now they made the new rares (e.g scarf and jester hat) untradeable. But they decided to keep the phats and masks and otha drops tradeable, i dont know the reason for this but i expect they wanted some tradeable rares. Like i said in my 2nd last post, rares are all about popularity, so the bunny ears are non-tradeable, but they still are popular
