Healers that don't want to DPS are like DPSes who refuse to move out of AoEs.

May I ask what keybinds people use for their dps abilities as healers? ...

I'd also suggest trying out Razer Nostromo or something similar. I've used that for years with G600 (even before FFXIV), feels way more natural than keyboard, and use thumbstick to move. Using thumbstick may take a bit of getting used to at first but it leaves four other fingers free to do whatever.

My binds are unstructured but I place the abilities that I use most (Stone III, Cleric Stance, Cure 1&2, Medica, Esuna, Aero 2 etc.) on mouse numpad (1-0 and - and +), then second most used skills (raise, virus, SS, protect etc.) on Shift + numpad, and whatever is left over on Ctl + numpad. Focus target is mouse wheel click.

You're probably already doing it, but i'll mention it anyway, mouseover macros make life a lot easier (e.g. '/ac "Cure" <mo>'), that way you can have the boss targeted and heal party member whose name you're hovering your mouse cursor over in the party list instead of having to switch targets for healing.

I highly recommend picking up a Logitech g600. It's a three click MMO mouse. What I do is bind CTRL to the third click and it essentially gives me 24 buttons all on the mouse itself. I then setup my hotbar to look like this:

The Naga mouse I have is basically the same as that. But even with 12 side buttons, I still have to put my dps abilities on some kind of modifier key, which means having to stretch my pinky constantly and strain it with pressing the button. THank you for the suggestion though!

I'd also suggest trying out Razer Nostromo or something similar.

I might look into that when I can afford to spend a bit more money on my computer, though right now I'm coming off about $500 of unexpected expenses for it. xD Gonna have to wait. But that looks like it could be helpful from an ergonomic standpoint. Thanks!
