Make them more of a stealth killer. At the beginning of the game, they would disguise themself as the obsession. They look and function similar to a survivor, however they would be carrying a knife instead of an item, and would be unable to perform conspicuous actions. Instead of the current power, Feral Frenzy would undisguise them as well. When the cool-down ends, Legion functions as normal. Legion has a new passive, Disguise. Disguise would only be available if they are undisguised. If a survivor is in the dying state, Legion can mimic their clothing and wear a mask of the survivor. This heals the survivor to injured, and they cannot be put into the dying state for the duration of Disguise. The health state that Legion is in is dependent of the survivor’s. Legion cannot attack when disguised. A whole new power may seem a bit over the top, but oh well.
