I have a range of [primary] professions at varying levels spread across my characters. So, I've taken this opportunity to make a quick spreadsheet of the skill levels I'm currently at etc.
As you can see from the table above only 6 of my characters have skill levels worth considering and only my main is both level and has max. skill levels. I keep telling myself I'll get around to leveling some other characters...
Back to the question at hand. So, yeah I have most of the professions. I'm only missing blacksmithing which I was intending to do on my monk and with the new changes coming think I will probably look into. But I guess the point, when looking at my characters, is that whilst I have a vast array of professions on the go very few of them are at or even near to max. level.
My favourite profession for gold making is definately engineering. I really enjoy making all the quirky pets and mounts and what's even better is that they sell relatively well on my server!
