In the PFH they said you could dye your camp clothes. Can you dye your armor as well? How about transmog?
In the presentation in the morning, Swen really quickly used some dye on a robe Gale was wearing. It was so fast that I didn't spit exactly what was happening or how the dyeing worked, but on the assumption that robes are treated like armour rather than camp clothes (which I can't verify but seems reasonable), I think things are looking hopeful for being able to colour armour as well.
I didn't see anything to indicate that there would (or wouldn't!) be full transmog, though as I think I mentioned Swen did say that armour would be hide-able and you could just wander around in your camp clothes appearance if you prefer that.
(As an aside, I thought the Gale's robe that Swen dyed was dead cool, and though it was at a later level and I think that we might have seen it in one of the trailers, some of the starting armours also seemed to have been improved. My ranger's initial leathers, for example, didn't look nearly so much as though someone had sewn them together in the dark and I really liked the design: it was simple, as befitted a low level armour, but just stylish enough.)
Yay for being able to dye armor! Thanks for answering all these questions! You are a superstar!😊🎉
