I hear that BS is one of the best professions for PvP as it adds an extra socket to bracer and belt. For this does it mean that it adds any kind of socket or allowing you to put any gem you want? Isn't BS rather expensive to level? I have no idea why BS is so popular, what are the perks to it aside from its socket bonus? I don't know what professions to do on my Warrior but I have 600 LW and Enchanting on my other toons so I thought I'd give BS a try but is it worth it?
