With a Necropolis, a Fortress becomes quite a formidable weapon. You need +1 speed for some breakthrough, quickly move it to the Fortress, break through, and then you can convert it back.
Also, does the Mullich bother anyone else?

You'd think Fortresses generate on every square meter. Nothing prevents the same Necromancers from upgrading Bone Dwellings for that +1 speed and then converting them back. This is usually done when there are still few Bone Dwellings, and upgrading them won't cost much anyway.
