Frost Witch disguises are physical, not illusory. They can't just melt away, as a Witch physically transforms into their newfound appearance.
How does this make sense? I understand where you're coming from, but suddenly my abilities are completely hindered to some arbitrary number just to 'give people a chance' to completely erase me? In my opinion, there's no reason why our redisguise ability should be hindered. Emotes are also a terrible way to measure something like this. Someone can draw a sword and cut off my head faster than we can do something that is normally entirely effortless?
I have nothing against the implementation of new lore and wards, but revelation wards seem to do the exact same thing as the previous anti-entry wards. To break a dark creatures disguise for four emotes gives them absolutely no chance to get into a city should they be a creature that can't blend in while in their true form. Now perhaps you don't have to get completely rid of these types of wards, but at the moment, I see no real counter, lest I want to attack something four to six times right in front of a city. I surely don't speak for all Dark Artists, but to implement this is to cancel out the one thing that makes the Fjarriauga playable outside of our boring ice cave.
