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

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.

Keybinds for those interested.

I use an mmo mouse so 1-6 on all bars are pressed on the mouse, uisng shift and ctrl for bar 2 and 3. The latter 6 on all bars are pressed uisng the keyboard and shift/ctrl.

Might change this

Up and down on the Dpad are the left and right back paddle respectively.

XHB 3 can the accessed with either LTRT or RTLT

First attempt to make panels for MMO mouse with 2 3x4 hotbars and 1 6x2 for utility

The VerHotbar

Hotbars for Lv60 Red Mage.

Single Target (L)

Mobs (R)

I created my chotbars to be comfortable, practical, and aesthetic.(to me anyway) Nearly all same/similar skills are in the same position across all jobs/roles while allowing for as little finger gymnastics as possible.

My XHB is split between chotbars 2(left) and 7(right)

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.

for each job, I create a "hotbar" that is basically a monitor for cooldowns/any spell/skill I want to see the status of; I also have a hotbar with Role spells & skills, and, Sprint. I would add Second Wind in the missing slot. I use Hotbars 2 & 10 but you can use any Hotbars you want.

for RDM, there are only 6 spells, so you could put them all on 1 column; I don't do this because of how I have my UI setup to accommodate multiple job setups.
