It was my understanding that the miners reroll was more of an upgrade if available. I.e. yellow becomes green, green becomes purple, purple become pink.

But if lets say green isnt part of the chain, there isnt a possibility of getting a purple or pink with miners, even if purple or pink is part of the chain. I.e. loot for the map is white, yellow, purple.

I also think vanity is on a seperate roll from the regular loot table, and it has to generate to the loot for the map at the beginning if it will even have a chance of coming out. Either luck enhancer may increase your chance of it coming to you by will never be a sure thing.

What I am intetested in finding out is if each time you start a map, does it generate loot for a team of 5 or only the number present at the start, then add for new entries? Or if someone leaves early is it removed? The real question is: are we leaving possible loot behind?
