This has no negatives besides your own private convenience. Long-term players already have every profession on their account which is bad for the community, as you don't have to rely on anybody but yourself. All the materials are from you, all the gems/enchants/glyphs and the craftable gear, from yourself, to yourself. I don't see how that is good thing in game where you are supposed to be interacting with other players. So with all due respect, please quit...and fast.
