pls update

Without the mod, 50% siege attrition happens but after so many turns that it's faster to just manually cheese every siege, win the battle, then let replenishment replace all the casualties.

Modded, the attrition still isn't instant, but it no longer takes so many turns to begin that attrition is pointless. The difference between the 3 different attrition versions is just how dramatically the enemy should be softened (with 50% version, it kicks in fast and the enemy practically vanishes if they have no armies around. With 25% version, the enemy starts weakening soon but takes longer before it's an easy steamroll situation.)

Isn't 50% the default attrition?
