The glossary entry for Dead End states "Although it will 'stop' a Borg scout on initial encounter, it does not prevent later scouting." This ruling has long hinged upon the concept that Borg "scouting" is a distinct concept from "mission attempting" that all other affiliations use.
However, in recent years, the terminology of the game has changed. Today, the rules for scouting state that Borg scouting attempts are "a kind of 'attempt'", while calling out that "it is not a 'mission attempt'".
The rules state that "missions are irrelevant". This is misleading at best, entirely incorrect at worst. What is actually irrelevant to the Borg is "solving missions". Most Borg Objectives still require missions in order to "complete objectives". Missions are the only Locations which can be targeted by Borg Objectives that allow scouting.
Missions are locations.3 Other types of locations exist, however, they are not targetable by the current array of Borg Objectives which allow for scouting at that location. When the Borg begin a scouting attempt at a mission, they are allowed to do so because that mission is a location.
The rulebook also alludes to "mission scouting (by )". This would lead any normal reader to assume that missions do have scouting attempts.
The text of Dead End states that the mission Dead End is placed upon "may not be attempted by a player with less than 50 points." As has already been established, missions are a subset of locations. Dead End, upon a reading of plain meaning and set theory, says that this location may not be attempted.
The text of the Dead End does not read "the player may not begin a mission attempt". It does not say that "the player may not begin a scouting attempt". It uses terminology which encompasses both of those and more: the player may not begin or continue an attempt of any sort targeting that location. An article from October 2020 elucidates that "cards that prevent you from scouting prevent you from starting scouting attempts, not merely from completing scouting".. If you were to invent terminology today that would prevent both mission attempts and scouting attempts from beginning or continuing at a mission while using the fewest words possible and being unambiguous, you could not do so any better than "the mission may not be attempted".
"The mission may not be attempted" should no longer be construed as applying only to "mission attempts". New players should not need to read side-bars and the glossary in order to discern that "an attempt is an attempt, except when it's not". Old players should not have clearly conflicting wording in the rules documents playing havoc with their memories.
The last benefit provided by such a change would be to provide one more mechanism for slowing the pace of the game. Recent tournaments have shown that Borg are now pace-setters for the "meta" of the game. Introducing this change would allow for one more piece of "tech" to slow down the Borg, when most others do not. The Borg are capable of ignoring almost every dilemma in the game. Introducing one single Unique dilemma which they could not ignore could go some ways toward setting a healthier pace for First Edition.
I have laid out my case for the benefits of these changes. I have not yet come across any instances where cards would break due to the change. Some other cards, such as Radioactive Garbage Scow would begin to affect the Borg. But, that's not necessarily a downside, either. Can anyone else think of something that would break if this change were to be made?
There is one phrase which would be made redundant: "cannot be attempted or scouted". This change wouldn't break it, but simply make the "or scouted" redundant.
