Blast from the Past; random thoughts.
The First Federation "CDR Balok" - a little help please.
General Trelane and his people could be "The One?" or a valuable ally.
Plus there are many others who could be "The One" or potential allies.
Why not fix and re-activate the Doomsday Machine; let Como Thu'fir fly it to the Iconian Sphere. Hail the Iconian's Sphere and say: "Say hello to my little Friend." Let the planet/sphere munching begin.
However, based on other things, especially the Sela recordings, I believe that Sela will drag something out of the Beta Quadrant that will help defeat the Iconians. However, once here, they will decide stay, hence a new enemy for the next season. Oh what a tangle weave that Cryptic has spun.
Note: Temporal mechanics always give me a headache. That said, one of my favorite episodes of Voyager was "Year in Hell" (Capt Nemo has a time ship).
In a "perfect world" I would like to see a new Season where we are not fighting someone or something. Why not explore, check out new planets, fine interesting new lifeforms, heck, even help colonize a new planet; do something else beside fight -- is it too much ask?
Lest we forget: "Space: the final frontier. These are the voyages of the starship Enterprise. Its continuing mission: to explore strange new worlds, to seek out new life and new civilizations, to boldly go where no one has gone before.
