I hope they will have BoP profession items that are not exclusive or better than other options, but are perhaps cheaper or more convenient.
Examples:
Alchemists get longer flasks and maybe bottomless potions.
Blacksmiths can repair their own items at anvils and pay less to do it.
Tailors can upgrade their bags to get a few extra slots.
Engineer gadgets have limited uses for non-engineers but are unlimited for engineers.
They should go with things like this. I hated having to level professions for combat benefits, but these kind of things would be great. Make me want to level the profession without making me feel like its mandatory for maxing my combat performance.
