if it helps, you only need to get to 400 engi. but the haste to gloves are very nice. although the rocket boots lose a little value if we're getting the passive 15% speed in cata, hopefully we are though.
Also, I'm not sure how much gold you have, but it only cost me about 7-8k to level engi and JC to 400
Thanks for your advice.
I'm not poor but I've saved some gold for eplic flying - that's it.
Around 6-7k overall. So buying these items is not possible.
(besides that a stack of mithril bar costs about 90g on my server and there are just 2 stacks per week in the AH)
You have your answer. JC/Eng or JC/BS are your best options. If you don't want to mine that much and you refuse to buy the mats then I don't know what to tell you.
But, honestly, if you powerlevel JC to 450 you'll be able to make back most of your money in a week anyway. It makes gold all on its own.
