There's a few reasons for this. As players note later in the thread, Blizzard is much, much better at itemization now than they were back when we were raiding Ragnaros. And we're all in 10 and 25 man groups rather than 40 man-- fewer people means fewer arguments about who gets what. Not to mention that there's so much more loot now (and so many more ways to get it), that even if you lose that roll to a Hunter, you still get Heroic badges to turn in, or you've still got your Arena rating to count on.
It seems like loot actually means a little less now than it used to, and that's a great change. It's too bad that the old "hunter weapon" joke might actually be becoming obsolete, but less loot drama means more fun, and no guildleader will argue with that one.
