There is no reason for you to see what other people get. All that does is result in other players becoming jealous of someone else and creating issues. Look at the DS LFR complaints regarding loot before 5.0 hit. I don't want to go back to that. I have yet to see a loot dispute in LFR since 5.0 hit outside of people complaining they got nothing but gld again. A lot of people don't understand the loot system as it is now so letting you see what others got would result in uninformed people just calling others ninja because they didn't see any rolls. So it should remain blind. If Blizzard does implement something, they should only list something like "5 out of 25 people got loot this kill". Who got loot and what should not be seen and should be left up to them to say if they got something.
From what I've seen in the game and in the world, you should never underestimate a person's ability to be unintelligent. Look at the warning labels on products. Hair dryers tell you not to use them while sleeping or while in the shower. Other products have similar warning labels because someone did something stupid that resulted in a lawsuit at some point. Blizzard's covering their bases with doing blind loot in LFR because a lot of people don't understand the loot system as it is. Back in DS, we knew who got what and people complained when others ninja'd loot they felt they deserved more. Now we have no idea who gets what and can't complain when someone gets an item we need but they don't unless they link it to us. If Blizzard lets us see who loots what, then I'll guarantee people will once again complain about being ninja looted in LFR despite that no longer being possible. A lot of people just don't understand even simple things. If you want another example from within the game itself, look at how badly some players DPS. They can't even read the tab in the spellbook listing what their primary spells are which would help them tremendously. Then there's those that just stand in fire and don't know how to assist a tank so wonder why they die when they pull aggro. Or those that don't interrupt ... or know how to kill adds ... or CC adds ... or stay out from in front of a boss who cleaves or from behind a boss who tail swipes. That's just a few.
I'd much rather avoid the drama that comes with loot, especially with a 25-man PuG group. It's bad enough in 5-mans. Leave it blind. People can't attack other players for getting loot they wanted while before people often attacked others. It's fine as it is. People attack Blizzard for lack of loot which is what they want, not other players for ninja looting.
