Castrum Queue and the overflow lottery

[Riyshn]

and the fact that the other marching orders are a 100% guarantee you get into the CE

-...-

Even in my personal experience, I have never failed to get into a single non-Castrum CE even once with marching orders up across around a hundred or two of CE's

Good for you, except you can't prove a negative. Meanwhile, I have had exactly that happen, so it is possible. And since the hotfix when queues have been overflowing I've gotten into all but 2 of ~20 CLL attempts, all with Priority. RNG gonna RNG, and confirmation bias doesn't change that.

The point is we don't know. The closest thing we have to official word either way is the initial patch notes when the system was introduced, which just says "Critical Engagements". And CLL is a CE, at least according to basically all the UI elements we have access to.
