Bracers are nerfed from 300% to 200% (maybe 250%). We also lose Ice Flows, hurting our mobile dps.
It also looked like Critical mass was losing the 10% increased crit chance for Fireball, Pyro, and Scorch, but it looks like it's simply increasing our crit chance from all sources by 10% (1.1), which looks to be a buff.
