Hi,I've been around here and seen lots of web sites of professions guides threads.
Anyways,I'm not looking for rep,just want u to know how easy it is to look for one.
1.Go to Google
2.Search "X guide level"(e.g. Engineering guide level)
3.go to website called: 'blizzardguides' in the search'd sites
4.enjoy
I've leveled my professions from there at the lowest cost and easiest way to.
Hope it helped.
