It's a question for beta testers.
I've seen a few WotLK recipe (with WotLK mats, cheap mats) that start at 350. But they all require a Runed Coblat Rod, which require 375 enchanting to be made...
It would be pretty lame if you had to level to 375 with BC recipes before you can lvl it with WotLK recipe. For example, Death Knights (who won't have any reputation with outlands factions) won't be able to lvl enchanting to 375. For that reason alone, I think the Runed Coblat Rod requirement is a mistake and will be corrected.
What do you think ?
