No "Death" trait for Huns.
The Huns have a trait called Death that prevents replenishment of your armies in any regions where a "horde" is present. The problem is that a single decadent unit of 15 horses, a remnant of a horde you just beat, STILL counts as a Horde. The effect? All the casualties you took in a pitched battle against the Huns won’t replenish unless you take your army outside of the region, leaving the region itself ripe for the Huns to sack and raze.
This mod aims to balance that, because the Huns already consume your food and have infinite numbers while Attila is alive, it just seems OP for the Huns to just send one unit to your region and suddenly all of your armies can’t recruit any more men.
I guess you could consider this mod a "cheat", but then again I believe the Death trait is a cheat on itself.
