From what I can tell they brought up other factors like contribution, potential value in future content and since we both agree that is kind of hard to objectively measure other aspect concepts. Role / job and if the group was able to the defeat the boss are the only factors that can be taken into account when earning a chance at a reward. With those two points in mind, how is it selfish / entitled that based around those two factors more or less everyone contributed equally to lead to boss being killed, so if everyone contributed equally why shouldn't everyone get an equal chance? If anything the old system was more selfish, both systems are not all that great tbh.
More so advocating for equal chance across the board, that is why I prefer token based system where everyone roles and they trade it said token for the piece of gear that they want. As Billy mentioned we are not in any position to tell someone in PuG (unless rules were agreed upon joining ) they are not deserving of something. That is going into how I wish FFXIV had more personal accountable / learning tools, that is not the topic at hand. Looking at it through that simple lens how can we really tell if someone had a larger impact over another? Unless you feel certain roles inherently hold more value which also does not fit within the vacuum since the game uses a holy trinity so ideally everyone works of one another, and also seems highly entitled.
You did say that the job is the only objective measure if that is the case we have two choices factor it as an equal or ignore it. If we ignore it then it really does not matter which system we use really. We really cannot measure contribution based off solely off role. Granted this is one denominational, but going based off how can we objectively measure ones contribution since within the trinity each role leads to the defeat of the boss. Now if you want to base roll priority off of contribution I would be a 100% down for that if we could figure out a way to objective measure it. The game works around a trinity and my view of a trinity is based how each aspect works off the other, thus they have different roles but equal contribution in a vacuum of coarse.
When you have different needs and people attribute value differently how is it less entitled to think ones "need" holds more value over another? Even if we leave contribution out and put the entire weight on role nothing else matters could said role have done the fight without everyone else in the group? Is a system that is based around giving everyone an equal chance at loot more selfish then what we had before? I mean they are better means to go about this all together and the greed all version is the worst one of all of them.
What I am saying since we cannot determine benefit, or use of an item I say we should leave it out the equation. Role in itself does not determine if someone is going to use the item that in itself is an assumption, if we value that why not other assumptions. Either way this whole thing would have made more sense if they just went based off a token based system and let people turn it in for the item they want. Though maybe that would impact longevity of the content.
I do have a feeling a lot of what I am saying is getting lost due to my poor explanations but I am trying. :P
