Forceful Rejuvenation Keybind
This keybind is another extremely simplistic one for my setup - basically all you need to do is hit V and find the Forceful Rejuvenation ability under the Archetype tab and drag it out to your Hot Bar. Do this for every single caster class that has Forceful Rejuv and then make a Macro on your tank to remember where you bound it.
For those unaware of when Forceful Rejuvenation is best utilized.... I personally save this ability for times when I am low on mana. After I use my regular spell harvest and start its cooldown I pop Forceful Rejuv on my team and then I harvest a second time for even more mana.
