Not sure if you're a controller user like me, but what I did that helped in so many ways in finding the new PVP Instants intuitively was create a seperate crossbar 1 and 2 for PVE vs PVP. A PVP/PVE macro swaps the two out. So the PVP res button is located on my PVP spec bar, at the same place where the regular res button is on my PVE bar. And then regular res is elsewhere on the bar, but at least this way I go to the intuitive place first.
