Chiming in to agree with what Joe said; your missions are way too long. Most people here do not have the time to read them, and that includes me. The entry level for reading your stuff is way too high.
Beyond that, I have to admit, you have another issue that makes me reluctant to read your stuff at all. In the chat, you tend to express an attitude that implies the onus is on everyone else to read your stuff, and comment, and you've been annoyed in there on several occasions because people don't.
When people tried to point out how long your stuff was, you brushed it off, and instead of taking it as constructive criticism, you chose to say you didn't understand how everyone else's were so short, and that your missions needed to be as long as they were.
That's not an attitude that encourages me or others to read your stuff. Entitlement is not the name of the game; we complain about it in writers regardless of whether they write fic or original works, so it's not fair to expect that sort of treatment of ourselves here, eiher.
Beyond that, there is a reason that missions are short; the attention span of the average reader and the fact that as a writer you can only take so much of a badfic aside. It also partially has to do with the goal of missions, as a story format in general.
Missions themselves are formulaic for a reason. They're part analysis, part wish fulfillment (Oh no! I used that dreaded phrase!).
You can't have it really be proper analysis when it's completely full up with plot. Making a mission have a heavy focus on a plot involving the agents results in the analysis either being lost, or the mission stretching out and becoming even longer than it ought be. When there's too much character progression in an individual mission, it removes the wish fulfillment portion. While agents might have their own backgrounds, personalities, and opinions, when character development and the analysis and wish fulfillment involved in a mission go at cross ends, the main purpose they serve in a mission- being our fill-ins, our window, our mouthpieces- fails.
Most people aren't skilled at balancing the two ends evenly in a mission or try to force it into the formula that we usually use. This results in stuff being glossed over or hastily shoved in, and a mission that's ultimately subpar. The average PPC mission is 'set up tone and feel, go into mission, complain about how horrible the badfic elements are, try to kill or otherwise do something about it, and head back'. There is not a lot of room for variety in that formula. If you want it to be plot based, or characterization based, you need to be willing to break away from it. Most people do not. Most people have not. If you want to have more focus on plot and characterization, then break away from that basic formula.
This whole problem, of course, is eliminated with nonmission pieces. It's why I do so many interludes, why VM writes cafeteria stories, why Dann writes DoSAT. The point with interludes isn't badfic or examining it, the point of those is character progression, and plot if you feel the need. Cafeteria stories and DoSAT and any of the departments that are not field based are the same. They are character and plot driven instead.
Huinesoron's Crashing Down and Reorganisation are both excellent- and long- novel length works. They both feel like very short reads, however, because they're legitimate stories, with a beginning, middle, and end, with character progression and plot. There's also the implicit knowledge that what you are reading will be resolved, and will have some sort of 'end'.
Wih novellas and novels, as readers, we have been trained to know that things will happen, and will resolve in some manner. Length- in terms of how a story works- is of little issue here, because plots expand and close, characters develop. It has to be the right size, but that can mean anywhere from ten pages to a thousand.
That does not work with missions. They are not stories in and of themselves. The spinoff is. You have arcs, and portions that can be definitely attributed as having beginnings and ends, but that isn't the same with an individual mssion.
If you read two random missions in the same spinoff, for the most part, you are going to not be able to tell what the order is unless they explicitly reference the others. Any character development? You aren't going to be able to tell. Missions do not have that focus.
The Sue is killed, the bad slash is fixed, the locations are untangled or set fire to, and then the agents head back to unwind just enough to be able to relax to the point where the mission sound off happens at the exact worst possible time. There's no real plot there. Characters are going to remain the same, for the most part.
Missions are, at best, scenes and chapters within a spinoff. They should not have to carry a full story on their own, because they are not a full story.
