I have completed a very shiny looking transmogrification set: Lightbringer along with the fabled GM 2hander. It wasn’t difficult at all to get. I ran the necessary raids once and got 90% of the set. The only ones that gave me trouble were the boots which drop off the first boss in BT. The 2h only cost me a trip to Netherstorm where the old pvp gear vendor is. Since I got up to Knight-champion during vanilla I was eligible to get the sword. The other way to get the sword is to get around 1800 arena rating which gives you the knight-captain achievement.
