Also with respect to Kiera RM,
It's actually a significant buff to her. The values were adjusted because she was too powerful. Try it for yourself before making hasty judgment!
She will devastate teams that do not move! (Please clear their resilience first of course

)
I think i will have to strongly disagree with this assertion. I have been an RM user for a considerable amount of time in arena, all the way from zedd to ronan then kiera after the revamp, and I can say with confidence that kiera rm cannot do any significant damage with the current meta.
First off, kiera rm has the weakest stat in terms of magic compared to the rest of the class. Its really hard to pump up its magic. I have been very successful with using RM in arena all the way until talents were introduced. My combo of ronan plus zedd, then kiera was a force to reckon with almost up until the time talents appeared. Ans just my observstion, ifelt the resistance to knockback was way over 30%, I think on average 50% is a closer figure. Talent system just crippled the RM's effectivity in arena.
Even aftet the initial revamp of kiera, I still tried to persevere with using RMs, sadly the damage output was considerably low fighting against top tier tanks, that was even before insignias were even introduced.
Overall, i believe RM needs a complete retooling of the skill. Most meta these days have at least 4cd or less. Having 5cd means you will face a stumbling block of zoey MW. A mystic that is not able to cast a skill is just a waste of spot in the squad. So it would only be very reasonable, that a 5cd skill for a mystic should and must have a devastating effect.
