That being said, I think it is much different than how it was in cataclysm. In cataclysm, you picked up tabards and did the straight grind of dungeons for rep. Because we ran so many dungeons in cata, gear came as a side product of rep grinding. Now, it's not the case.
I cannot tell you how many mail pieces have dropped in my group, I have lost count. Best part is - Nobody can use them. I understand that this is WoW, and that 100% smart loot would ruin the random drops; I get it, trust me.. What I do not get, however, is why they cannot add in a little algorithm that just decreased the chance of loot that was unusable by the group to drop. Seriously, I have other things to do in MoP.
I like the dungeons, and overall the experience of MoP as a whole. I just think, with the increased world required activity, that it should be a bit easier to gear up in heroic dungeons. I am not talking about this applying to raids, only heroic dungeons. If anything, give an option to veto 1*Boss# items per run - disallowing those items to drop.
A veto system would allow players to at least control, a tiny bit, and prevent or decrease the chance of a specific item dropping and just instantly making the group annoyed. Once I start doing heroics on my alt, I hope to god I'm lucky!
