My main is a lvl 26 Necro and is tougher and more solo friendly than my lvl 26 Guardian alt. I'm not sure if I want to keep playing the Guardian in combat or just use him for crafting. I guess I could pick up tinkering with him, since the Necro has transmuting, but I'm not sure what tinkerers make.
The Guardian's crafting is level 21 armorer. Armorer makes sense if I play him as a combat alt. If I just go with the Necro, I'd want to switch the Guardian's crafting to Weaponsmith, to benefit the Necro. Since the Guardian is only level 21 and just recently declared a specialization, it would be a pain to start over just to declare as a weaponsmith. Is there a way to change within the same "family" of tradeskills that doesn't involve starting over?
