These are my RDM hotbars, very much a WIP, Hopefully you enjoy :)

Almost Entirely Based on boatium's Personal MMO Mouse RDM: https://www.xivbars.com/job/RDM/5141

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

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.

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.

Just copied Nanaki's

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

XHB 3 can the accessed with either LTRT or RTLT

Probably a WIP

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

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)

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

Single-target heals on left, damage and damage buffs on right, buffs in center, and AOE heals on double-right

SHING SHING SHING

Damn, this is a lot of buttons.

Finally

'Twas I who fought the dragon

Boom boom bakudan

Splorp splorp splorp, pretty picture!!

Mysharona

Like paladin but edgier

Basic skills on right, AOE on left, buffs on cross.

Something something Hokage, Believe it!
