I'm pretty happy with my layout, but some of the screenshots I've seen of this game are disgusting. Some people have ui elements everywhere, including the middle of the screen. Dunno how anyone could play like that.
This is me in 24 man raids because I never bothered to resize or move the Alliance raid meters so they were always in the middle of my screen taking up a ton of space.
Here's what I came up with after mucking around a bit.
I play with 1600x900 so I don't have as much room to play around with compared to most people that seem to be running higher resolutions.
First one is when I don't have anything held down. My crossbar only shows up when I'm holding R2 or L2 to use something.
Second is when I have R2 held down and third is when I have a focus target.
I shrunk down and moved the alliance bars off to the side right above the quest tracker.
Buffs are right above the focus target bar. Moved that off to the side too since I don't really like having stuff blocking the center.
I see a bunch of people having their target bar at the bottom towards the center and I couldn't do it.
I'm too used to having a big health bar at the top for when I target stuff so I left it up there since it's not obstructing anything.
