Should be easier on my hands...

My basic Summoner hot bars

My main Scholar layout

Might change this

Updated for Dawntrail

Buttons consistent for similar job actions (Dye = Potion)

Hotbar 1: White mana on the left side, black mana on the right side. Single target above, AoEs below. Both/neutral down the middle. I used to put acceleration on Hotbar 3, but it's better this way for quick succession to the relevant actions.

Hotbar 2 (ctrl): The 1-2-3 melee combo on top. I usually have my gap close/make on those two middle positions. Sleep, lucid, cure, and the DPS buff are just rollovers from my old hotbar as Summoner, my first job, and that was before I put more thought into hotbar setups. AoE and run+gun spenders on the bottom row.

I have my hotbars set up so that pressing R1 toggles between hotbars 1 and 2, with hotbar 3 as the WXHB.

"1" icon is Aether Compass, "2" icon is Gysahl Greens.

Black is right, white is left. there's still a lot of flexibility here, but this is more or less what works for me

The VerHotbar

Pot goes on Bar 3 Down D-Pad Raise uses Macro

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.

Just copied Nanaki's

RDM as of 6.5

Hotbars for Lv60 Red Mage.

this layout works for levelling from RDM unlock through Dawntrail. main crossbar is your single target spells & burst rotation, and the 2nd has your AOE spells
