I was going to take up Eng recently for the goggles, but they'd soon get replaced it seems. LW is nice for a few pieces of armor, but that'll get replaced, and then comes the enchant which is nice, but every other profession when boiling down to just 1 enchant or stat bonus, all seems to be the same.
So it's really whatever works for you, eng at least has toys to spice it up.
Outside of toys...
Inscription - 104ap 15crit shoulders
Leather - 114ap bracers
BS - extra socket
JC - bop gems
Enchant - 32ap to each ring
Alch - stones
Skinning - 25crit
Mining - 500health
Right now I have skinning just for leveling, and in all honesty, looking at the similarities between most profession enchant wise - I might just go with mining since nothing really stands out as TAKE THIS OMG. I've got tons of gold with not much to spend it on, so if you're in that boat as well, picking up just about any profession works, but there isn't too much BOP that really separates any from the others.
