NOTE: The "Stance" key there is for you to replace with your Draught of Strength since I couldn't find the item on this tool.

1 is normally mapped
2 is usually Ctrl + {Number}
3 is usually Shift + {Number}
4 is usually Alt + {Number}

This is build with the optimal opener and rotation in mind from The Balance Discord. Essentially, you can braindead your opener and tap over for your oGCDs pretty easy with this. Also your 3rd bar is pretty much for AoE and rare use keys.
