I am not a great tank, but I do play WAR in solo content at times and this is the layout I came up with that works for me. Not updated for 7.0.

Althea's WAR layout

altheavalara

This is very likely a tweak of one of Squintina's WHM layouts - I was heavily influenced by her when I started playing WHM. I have changed some things to better suit my style. Updated for 7.0.

The Dye icon on hotbar 3 is Eurekan Potion, as I sometimes do play WHM in Eureka.

Althea's WHM Layout

Single target on chotbar 1, AoE on chotbar 2. I change using the right bumper button (R1) and sit on the chotbar as needed. Possibly based on Squintina's layout with tweaks, I can't remember if I got my original layout from her or not. 

Not updated for 7.0. Putting this up for a friend (and so I can transfer my chotbar to my alts)

Althea's DNC Layout

Putting this up for a friend. I'm not a great tank so this is probably not optimal and/or is missing stuff. Not updated for 7.0.

Althea's PLD Layout

A first run of a layout, influenced by my SMN and RDM layouts. ST on hotbar one, AoE on hotbar 2, other stuff on 3. I usually sit on either hotbar 1 or 2, depending on my needs, and switch between them with the R1 bumper.

Tweaked on 7/28/2024 - I added Rainbow Drip to the main two bars because it has a proc mechanism at times - you need to see that, not have it hidden on third bar!

Althea's Picto Layout

A SMN layout that makes sense for my brain and how I play. Single Target on main, AoE on hotbar 2, which I usually switch to by hitting right bumper (R1) and then staying on that hotbar as needed.

Updated for 7.0!

Althea's SMN layout

Based on Squintina's layout, but with tweaks that fit my brain better. ST on chotbar 1, AoE on chotbar 2. I hit R1 (right bumper) to change to the AoE and sit on that chotbar as needed. Since RDM is my Eureka job, I have Eureka Potion set to chotbar 3, LDU.
