I have tried a lot of different setups on my Templar, but I cannot get higher than 117k. I included camera footage in this video so you can see exactly what I am doing, please let me know if you have any tips! https://youtube.com/watch?v=HEkaw-ZE0dc
Not a parse fiend like some players, but does it really matter if you can "only" hit 117 on a templar? Nothing in this game requires you to stand still and inflict mass damage while not taking damage or avoiding mechanics.
