I once again find myself bored and wanting to level an alt. This time I've decided to brush off my long unused level 30 shaman. Currently she has mining and skinning but I'm thinking of dropping skinning and taking up either jewelcrafting or engineering. I already know about engineering (I have another engineer already) but I know very little about jewelcrafting.
That brings me back to my original question. What exactly are the ups and downs of jewelcrafting? I know that they can make some jewelery and trinkets and cut gems, but how useful is that really? Are the rings/necklaces/trinkets actually worth using? Does cutting gems myself do anything for me over buying from the AH? Will I go broke leveling it and having to buy what looks like 9346528345 different patterns?
Any info or advice would be much appreciated.
