What is this word salad? From what I can gather, are you suggesting that the hierarchy system that basically every business on the planet uses is communism? Master Looter effectively allowed people to use different loot systems to assign gear in different ways, such as round robin, DKP, GDKP, Loot Council, and of course the dictatorship method. I find it hard to believe that anyone could argue in good faith that a purely random loot system that prevents people from trading gear is the best system for everyone. That's exactly what the Bliz devs did though, and no surprise, a lot of people hate it.
I'm also unsure what the heck you're talking about as far as your idea of capitalism. Capitalism is about the private ownership of the means of production AND their operation. This means that guild leaders/owners would get to decide how to distribute the profits from their ventures, and that the people joining said guilds are effectively signing a contract agreeing to said distribution method. You instead are coming in here trying to dictate how they distribute loot because you feel the raiders/workers have a stake in the guild/company and therefore deserve part of the profits regardless of what the owner wants.
I can't tell if you're greedy, self absorbed, or dishonest. Maybe you're just ignorantly good natured and don't trust a free market to weed out toxic guilds (which is what happened in the past). I'm just glad that whatever the reason, Bliz isn't listening to you anymore and is going to allow guilds the ability to decide how they function for themselves again no matter how much you want to whine and moan about it.

At least for dps, this assumes that people are equally skilled, which is obviously not the case. A piece of loot that sims at +500 dps might get your top dps +450 and your bottom dps +200 because they are just a worse player. Have you ever once looked at the huge difference in logs by ilvl? This idea that gear is the great equalizer is so obviously dumb that I don't understand why anyone still bothers to push it. I know people want to believe that if they had 280ilvl that they could be one of the top players in the world too, but that's just not reality. I consistently meet players with about 270ilvl and 4pc tier that do half the damage some of my raiders did in SoD.
Even for tanks, it's probably a good idea to evenly gear up tanks since we need 2 of them for basically every fight, but it's also not a bad idea to overgear one tank and cheese certain mechanics or bosses almost completely.
