There are two known bugs with Chains of Ice that should be hotfixed today (Dec 11) or possibly soon after that if something goes wrong. (Stupid caveat that I have to put in everything I type now: this is not a promise of when it will be fixed; only our intention to fix it when we can.)
First, there should not be a target limit. That is, the single limit nerf you are seeing now was not intentional.
Second, it appears to not be functioning correctly with Endless Winter. The disease is not being applied at all against snare-immune targets. The intended behavior is the snare is not applied, but Frost Fever is.
Unless I am forgetting some change we made early on, the design intent is that Chains of Ice functions as it did before 3.3 shipped.
