Couple of updates to get to in this post, so bear with me on the length. First off, last Thursday, Method took our weekly trip through Molten Core. For the past 4 weeks or so, I have been on top of DKP to get the Giantstalker's Leggings and Giantstalker's Helmet. They were all I needed to complete my 8/8 set. I had hoped that at least one of them would drop, preferably the helmet, as I still had a green helmet. To my surprise, both the leggings AND helmet dropped, completing my Giantstalker set. The 8/8 set bonus is AMAZING to say the least. 15% damage to Multishot and Volley means I probably won’t even be equipping any Dragonstalker I get until I get the full set.
I would say that the next most important pieces of gear for me, would probably be 2 new weapons (hopefully a Doom's Edge, Core Hound Tooth, or Brutality Blade), a good necklace, and maybe another good ring or two. Of course, if any Dragonstalkers gear drops, I won’t pass on it
