Shiradi Champion is supposed to be a ranged/caster focused Epic Destiny. You guys just completely floored casters taking Shiradi Champion.
Fortunately for me, my Shiradi Champion toon is primarily ranged, but I can't overlook the extremely overly nerfed change this patch from 30% chance to trigger Prism and Stay Frosty/Good with spells to a mere 5%, Prism spell power scaling from 100% to 50%, and Stay Frosty/Good spell power scaling from 200% to 50% on top of that. You nerfed the power of Shiradi Champion's Destiny Mantle for casters by 1 - 0.05 / 0.3 = 83.33% for activation chance, 50% for Prism power scaling, and 75% for Stay Frosty/Good. If my math is right, that's a 1 - (0.05 / 0.3) * (0.5 / 1.0) * (0.5 / 2.0) = 97.92% nerf to the power of Prism and Stay Frosty/Good for casters.
I think it's time for me to switch and just splash some Shiradi Champion, because it was already kind of weak compared to a lot of other Epic Destinies in my opinion. Now it's laughably so. You're beginning to undo the good changes you made to Epic Destinies. Hopefully, the upcoming update will include a correction to this over nerf.
