Why not give us a complete breakdown of each of the MISC choices with their Pro's and Con's? That might help to clear up some of the confusion among the fandom on this thread.
Here's the best I can do....
[ ][MISC] The surprising advances of House Bene are concerning, and you should try to look into them.
House Bene and House Tartesis are the only two Houses really left in contention to rule the Empire. House Taresis is our preferred candidate (because we're told they are 'noble') and should have the advantage because they're much richer, but House Bene seems to be doing unexpectedly well. This option would let us investigate why, though we won't know until we do if there's anything to be done. Some posters suspect (without any particular evidence) that Bene is supported by the Romulans.
[ ][MISC] There are rumours of an independent research house rimward of Gammon, carefully hidden away. It should be investigated.
Obviously uncontrolled mentats are the reason for the war, so an "independent research house" that is "carefully hidden away" is cause for concern. We've seen what they do in public... what do they feel the need to hide away? Of course, rumors may be just rumors and maybe there's nothing there.
[ ][MISC] Reports of a Honiani tramp moving through Arcadian space should be looked at.
Why is a Honiani ship moving throguh an active warzone? Seems most suspicious. Maybe it's there to evacuate mentats and their technology or Operation Paperclip them or something similarly worrisome.
[ ][MISC] Linderley's team on Morshadd could be the nucleus of a useful asset if you can reinforce them.
Having an active Intelligence team on the homeworld of the Arcadian Empire could enable us to get improved intelligence and allow for active operations there. Could be very important during peace negotiations, as they try to spy on us and we try to discern their intentions. Combines nicely with the investigate House Bene option.
[ ][MISC] Start a discreet program of tachyon tracking devices along the main routes between Arcadian star systems, like in Orion space.
If the Arcadians get up to something we won't like, they'll use starships to do it. Knowing exactly which ships are coming and going from their systems could help uncover plots. Also, if there is indeed Romulan interference, we might spot some cloaked Romulan ships.
[ ][MISC] Continue to establish protective outposts in fringe Federation systems
We've seen how much outposts can beef up a planetary defense. Not only will this strengthen us against potential mentat raids, but we get to keep these outposts after the current crisis ends and have them for the next crisis. Could be very important if things ever go hot with the Romulans.
[ ][MISC] Have retired Admiral Kahurangi start appealing for recruits for Starfleet and the member world fleets.
Starfleet is in desperate need of more Officers, to the point where we might end up having to delay the (re)launch of ships due to not having enough crew. Kahurangi boosting recruitment could help with that.
