The hunter / shark plots need to be more overt when they fire.
I'm really not digging having to randomly guess why suddenly I have a dozen arty guardians appear out of no where, or that hunter killer.
The shark plot already tells you when it gets a bump (the AIP from human command station death, etc). That's the exact moment it launches the mini-exo that goes along with it (it doesn't save those up). It does save up its impact on the next CPA, but when that CPA launches the text describing the count of each mark launched also includes a line for the shark contribution. Is there anything else you want it to say?
The hunter doesn't but all its doing is putting extra units into the special forces. What do you want it to say, "putting extra units into the special forces"?
I can certainly do that but it seems like more information than the game usually gives (outside of logging; advanced logging will be happy to tell you about every single hunter unit added, in the SF log). Would you want the champ-nemesis thing to tell you when it spawns a SF or TF nemesis, too?
More pain, no gain, no way!
I don't think AI Plots, in general, are for you then
I don't think Avenger, Hybrids, or Beachheads give any in-game benefit, they're just there for those who would find the game more fun that way. Same with the new Hunter and Shark plots.
Minor Factions are where we try for the silver lining thing, though some of them were added without that in mind (Preservation Wardens... can't think of any others off the top of my head as Marauders, SCLs, Roaming Enclaves, ZTraitor, Dark Spire, etc all have some potential benefit... Mining Golems are pretty much just penalty though).
