I was playing with my character settings for displaying character's names and noticed they have the option to always show, always hide, show when targeted and only show during battle.
I get why the last one is useful when in a party or alliance for mouse + kb, but i would find the opposite more useful for a couple of reasons.
As a PS4 player with controller, i won't mouse over characters to select them, i'll navigate the party list with the d-pad, which always shows names and health bars.
Second, with more players i get my screen more cluttered. 8 man isn't that bad, 24 man starts to be a mess and eureka can be a pain, it gets to the point where i sometimes miss some monsters telegraphs. I tried always hiding all names but then the world seems empty when i'm in a settlement or city.
It doesn't make the game unplayable, but it would be a nice QoL improvement.
