I second this idea. I've seen it done in other MMOs. I don't think I would use it myself. I use a controller for FFXIV because it's much more comfortable after a slight learning curve with target selection. Another idea to consider that some people do for FFXIV, which I found bizarre, but cool, is going all keyboard with no mouse. Here's an interesting video showing it off here: Beginner's Guide: How to play FFXIV with Full Keyboard/Piano Mode (No Mouse!!!) - Angelus Demonus
