While I would enjoy being able to cross-transmute armour, I’d be content with just being able to transmute armour to town clothes – I really like that idea, as there are a lot of town clothes I’d like to mix with armour for certain looks.
I can understand the PvP concerns with cross-transmuting armour, however they already have an fix for that, and it’s used in sPvP – just have a PvP specific armour that comes up an WvWvW. Cus really, in PvE…why would you care about what class someone is that you’re just passing?
