In the past I was strictly into Arena, but now I've decided to get into RBG and my guild has asked me to build a FC offset. I've read numerous things about gemming, some say to gem mastery, some say pure STR and some say strictly resil. I myself was going to go with a mix of mastery and resil, any input on this? http://www.wowhead.com/talent#sZGMGcRddRRucbM:skodqoMzm is the spec and glyphing that I'm considering, any input or suggestions on that as well would be welcome.
