tl;dr they already told us why they wont let us send mail to our mules, its called RMT.

so you can blame the gold farmers for you not being able to mail yourself stuff between characters.. besides.. get a trustworthy friend and start doing it the old fashioned way or just sell off the stuff. i have all DoH 50 and still manage. you don't need every single kind of material in the game to use all your jobs. you just need to learn to prioritize, otherwise one can be called a pack-rat.


Your given 100 (personal) plus armoury crate (so no equipment in your personal)
175 x 2 for your retainers.. and 40 (2 x 20) in your bazaar that you could overprice if you really needed the space, and an Armoire in your inn room for seasonal stuff.

what more do you really need?
