With war looming on the horizon with the wolves, maybe it's not the ideal moment to put your scheme to execution? not the best moment to upset the entire chain of command and possibly demoralize the troops...
Or is it on the contrary, the best moment to rid the army of an incompetent fatso general who got there purely through nepotism? Imagine... this fool just leading our glorious troops during peacetime already makes my skin crawl. But him leading them into massacre after massacre, and us sitting there until the Coordinator cans his fat ass... How would that be for demoralization?

But in the meantime, maybe your rival is plotting as well and holding the same sorts of grievances against you. Only one way to know..
