Ice Spirit is currently ranked 5th in pick rate, and the current proposal seems weak for a nerf. The freeze duration should be increased from 1.2 seconds to 1.0 seconds, and the reduction should be increased by 17%.
I think the 12% HP buff for Ice Golem is too much. Buff only 6% HP from 1198 to 1270.
Ram Rider is also low in pick rate, and P.E.K.K.A evolution is increasing in pick rate, but Ram Rider is forgotten. Her HP should be buffed by 4% from 1696 to 1767.
