I worry this would remove some of the work that has gone into preventing meta regarding disguises. As it is it is not uncommon for some players to simply approach a disguised player for "being suspicious" based simply on wearing s disguise items bthat are incredibly common amongst the ambient population, even with the latest efforts to reduce meta. Giving those kinds of players the tools to just randomly strip someone of their disguise without engaging in RP is something that concerns me.
I think this is not necessary because there are already systems in place to cover these types of actions.
The system is going to assume that someone who is disguised is going to do everything in their power to remain disguised.
Disguises slip over time depending on what the characters wearing them do. One of the things that causes disguises to slip is combat.
If a character wants to see who is under a disguise, they can engage in combat and handle the interaction that way. (grapple, strip, etc.)
It seems to me like a command to dodge around combat is just ripe for abuse.
In comparing two hypothetical characters with the same total UE spent, a character who has spent UE on the ability to disguise themselves is going to be disadvantaged against a character who focused purely on combat.
To grant a character who is fully focused on combat yet another tool in their arsenal to reveal disguised characters seems imbalanced.
If the GMs hadn't recently given carte blanche to accost characters who you think just, might, maybe, perhaps in some way be the person you are looking for, I might be able to see the value in an 'undisguise' command. But given that the bar has been significantly lowered for accosting disguised characters, I feel like having to 'defeat' a disguised character through combat is a fair trade off.
Do you disagree?
