Lets not mischaratize what the blue post said: “This is a good topic, and a difficult one because it gets to a lot of questions about varying player tastes. No definitive answer–and we want people to keep talking about it–but a few thoughts:” Is the heading for that blue post.

Also since we are talking about it lets talk about this bit:
“One of the most difficult aspects of this topic is social tension. Sometimes people argue with their teammates about buffs. It’s very understandable, to me, why one possible response someone might have for that is–this can put you at odds with your own groupmates, so stamp it out. The flip side of that is: this is part and parcel of playing with real people in a large cooperative group. And preserving the human element of group play in WoW, not boiling it down to predictable mechanical interactions, is an important value. See for example, the common lament that group-finder content has lost a lot of the human interaction from the experience. Mechanics that involve interacting with groupmates bring out both the good and the bad of that, and that might be better than having neither.” Source: External cooldowns/buffs on other players in group settings - #13 by Sigma-11129
So our blue friend Sigma wrote this in the community council forums and with apologies I must say its a very silly idea. To sum it up they recognize that it can cause social tension and even “put you at odds with your own groupmates”. But this is a social game, and people say they miss socializing, and mechanics like this bring out the good and bad and that might be better than having neither. … uhhh ya we so enjoy getting mad at eachother that is the quality game play we look forward to and enjoy so much and tell stories about to our friends how we didn’t get PI all tier even though the other rogue did and it made it so angering and frustrating to me. Again, they are trying to play devils advocate, but whatever good feelings come from PI are heavily outweighed by the negative feelings. And if Blizz really wants there to be fewer people into raiding this is a great way to do that.
