It's just like vote abandon or kicking a player from a duty. People don't read, and agree to everything that just pops up on their screen, so some do not even notice that they are joining a loot master party, hence the drama during or after the runs. Others don't mind joining these kind of parties, if they are just looking for light farming (old relics), or tomes, WT etc. At least you can make plenty of players upset, following this kind of strategic, sometimes that's the most entertaining part of the whole game. I personally think, that if a player can't be bothered, wasting 2 seconds of their time and reading the PF description, they deserve being in a party that gives only the leader a mount, or is up to the mercy/courtesy of the party leader. But after all there's no specific logic to that lol
