PTR 3.0.8 Notes - Guide updates

I almost finished updating the guides on the site, now there is only Herbalism and Skinning left and the secondary professions. I did not make a post about it, but the other primary professions are finished. Go and check them out:

• Alchemy Guide
• Inscription Guide - I corrected a lot of errors and made some changes.
• Jewelcrafting Guide - Revamped some of the pre-WotLK part.
• Leatherworking Guide
• Mining Guide

There will be a LOT of changes with the new 3.0.8 patch. Too bad there is not many new recipes, and the new ones can be learned at max skill level, so there won't be much change in the leveling process. However, there might be some undocumented changes with the skill ranges. Please post comments or send an e-mail if you found something that changed on the PTR and it's not on this list.

If you look at the Blacksmithing section, they mention "Increased the materials required to make several recipes that require cobalt." I didn't check it out on PTR yet, I am currently downloading the client, but I assume it will be [Reinforced Cobalt Chestpiece].
UPDATE - It's the Reinforced items. MMO-champion confirmed it.
