Yeah... Out of the three hunters in our guild only one has this bow (and that's not me, seems I'm stuck with my Melmorta's forever as crossbow/gun never dropped either :)). We have 3 Kara raids, and one of our raids saw 3 drops. The second time it went to a rogue and the third one was DE'd. It never dropped for my raid at all though we had 3 Malchazeens in a row once. It was kinda fun when that rogue took out his bow to tease us and I walked to him and took out Malchazeen which he wanted as badly as I want the bow. We had a good laugh over it :)

Well guess I'll just keep trying and hoping. Drops never seem to be fair, it's just that sometimes they go in your favour, sometimes in favour of others. Out of our 8 Gruul kills up to date we got 6 Hero tokens (3 of which went to the 3 of us) and two Defender tokens, so I'm taking comfort in that though I feel sorry for our rogues/palas/shamans.
