Currently I have:
375 Mining/JC (Paladin)
375 LW/Skinner (Shaman)
375 BS/Tailor (Shaman)
375 Herb/Alch (Shaman)
375 Enchanting (Shaman) - I have the mats in my bank to power level Inscription to almost 350 as of the current beta build.

I feel having all professions will be a huge bonus to me, since I will not have to deal with as many other people for things that I need made. The only problem that I may have will be the daily quests for professions (JC for example). Hopefully it all works out!
