I have to disagree with a lot of people here. I am sick of the lowest dps, the slacker healer or the tank that dies three times on Ultrax because he can't click, getting the loot. So I will need and pass it to someone who deserves. I still only have a chance of winning, and if I win, I have the right to do with it as I wish. LFR isn't about gearing, it is about allowing casuals to see all the content, so those players who work hard to carrying a bunch of other people through should be rewarded if I can help it. Though, the highest DPS on things like madness or Yor tend to be the ones who do not swap targets, so I actually look at their charts, and if they actually helped and didnt just sit there, I will give it to them.
If you don't like me passing the gear I win to those who deserve it, then create a 10 man or 25 man grp, lead it, and try to kill some bosses. If you succeed you can pass loot out as you so desire.
