Single target on RT, AOE on double RT with D-pad combinations mostly the same for both situations.

2nd most used skills are on LT and double LT with face button combinations

WIP for current warrior hotbar. Expanded XHB is enabled both LT - RT and RT - LT are set to Right 2. This allows for easy access to mits/healing regardless of which side of the HB you are working on. Right side for single target, left side for AOE, top bars for lesser used actions roughly based on the single target/aoe split.

MMO mouse setup with modifiers.

Note: Sprint and Limit Break should be on a Shared Hotbar!!!

RB toggles between 1 and 8 for AOE

Lv60 Warrior Hotbars

WAR Layout 6.55 (Not 7.0-Able)
LT>RT remapped from Set 8 Left to Set 8 Right, only right half of Set 8 is used
Set 1 - Primary Skills / Defensive CDs ; Set 2 - Utility + Situational CDs ; Set 8 - AoE / DPS CDs / Major Defensives

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.

Hotbar 1: The good ol 1-2-3 combo on top, then the single + AoE oGCDs along the right side, then the legacy spot for Sprint. Next row down is AoE 1-2 combo. Then next row is the ranged and gap close, which thankfully still works as a free damage button in 7.0. Then the two bursties.

Hotbar 2 (ctrl): A few oddities in here. Top left is the burst hitter. Next is technically the alternative 3 in the 1-2-3 combo, since it felt more fluent to press 1, 2, ctrl+2. Next is the single-target spender. This was just built on the rotations as I leveled up and placed these actions accordingly. On row 2, bloodwhetting and the AoE spender just had to be neighbours. Row 3 has the job-specific mitigations, although now that I re-read the tooltip, Thrill and Bloodwhetting could be great vertical neighbours. Row 4 has the straight up heal, low recast time shield-a-friend, and team shield.

Single Target (L)

Mobs (R)

I show Cross Hotbar 3 (Left) with both of the expanded trigger controls, so you can easily add in another 8 actions if you prefer, I use XHB 8 as a shared bar between all classes for traversal and general actions outside of combat. Role actions are consistent among my layouts, and so are general actions. The macro icon is a placeholder for a Tincture/Gemdraught.
