The main advantage of asset quality in conflicts is to do more damage in extended tasks. This is a clear advantage in:
Duels (doing more damage to your opponent)
Skirmishes (doing more damage to notable characters)
Warfare (doing more damage to enemy assets or notable characters)
Intrigue (doing more “damage” to notable characters)
However, in espionage, it seems less clear how asset quality plays out, since you’re more concerned with moving around and gathering information than doing damage to people. The rules contain a comment that high quality spies/agents etc wouldn’t need a bold/subtle move to bypass lower quality security measures. However, since all actions have to be bold or subtle anyway, this passage seems redundant.
What would be the advantage of a high quality asset in an espionage conflict? Somehow I feel it should be to make getting it past security measures easier, but I don’t see how that works.
