Replaying Attila - mod recommendations?

Recently started up Rome 2 again, but found it a bit too easy. I also always liked Attilas style and atmosphere, even though I didn't play it that much. So I was thinking about starting it up again, but wonder what mods you might recommend that tweak the game a bit. No need for total overhauls, just little qol stuff and slight balance changes. For example I remember using a mod that made towers less of a threat by reducing their fire rate. Also always got annoyed that units were automatically upgraded. Stuff like that basically.
