Changed my DK from Horde to Alliance this patch, but a major issue is that it’s borderline impossible to get anything made via the Crafting Order system due to me not being able to communicate with the trade chat on a server that is mostly Horde players. This really needs to be looked at, if you’re actually serious about cross-faction gameplay.
Only way to circumvent this now is logging on a Horde character to arrange the work order and then relog.
