There's also this really succinct comment

"XIV could also stand to center and make more prominent useful or required UI elements. It's really silly that the target frame is jammed at the top of the screen along with all of its buffs/debuffs and cast bars when looking at that is a major component of any fight. The party frame is also waaay too far to the left to keep your attention on both it and the fight.

There's probably a whole video that could be done just pointing out how XIV's default UI layout is flawed and clearly build more for immersion/keeping things out of the way than being useful in any sense in content. It is great that everything is moveable though, took WoW 18 years to do that without addons.

Here's an old but still relevant video from Preach (MMO content creator, WoW focused at the time) that applies to any UI in any MMO even if the video is WoW-centric about principles and attention splitting and layout and stuff. SE could set up players for success by default better than they do in this regard, even if they're good at letting you customize after the fact."
