Actually, I have a couple toons I've been running LFR with. And the fact that this already happens is entirely my point. Unless I'm gravely misinterpreting something, the major reason for this change in loot rules is to alleviate the frustration such practices cause to players who are rolling on loot because they actually intend to use it. The "top X rollers wins" as you said, does not make things worse than it is now, but it does not particularly HELP, either, which is why I dislike that option.

There are, of course, issues with the other mentioned possibility if it's taken at face value. As pointed out by Pyromelter in another comment, if it's simply "Anyone who rolls higher than X wins loot" than it's possible for everyone to get loot off a boss and it's also possible for NO ONE to get loot off the boss. For exactly this reason, now that I've seen the issue, I don't think a system that works like that would be suitable, either.

In the end, I don't think whatever system Blizzard decides on will be quite so simplistic, and I'm sure they will carefully consider the pros and cons before making a final decision.
