I've been twinking for the majority of my time playing Wow. I've yet to come across anyone actually using Sfang or Gloomshroud at 29 and being a good player, let alone beating me with them.
Also, it stands to reason that an item with more stats is better than an item with less stats. BoAs have more stats, and therefore, are better than non BoAs. Glass cannon is pointless and people who argue in favor of it are retarded (or lazy). 'Play style' is how you use your abilities compared to other people of the same spec. It's not choosing one piece of gear over another.
Calling me an idiot when you don't know me is a surefire way to make yourself look like an idiot.
