DogSoldierSPQR Actually I think there is a problem with slinger becouse they still do to much damage to heavy armoured infantry with shield.
I have done this simple test:
Rome VS Rome
using one of the best armoured troops of the game.
I keep the unit in position without using testudo or shieldwall
Custom battle:
1 Test) 1 cohort (200 men with your bigger size unit mod) VS 1 roman archers unit
after shot all arrows they loose 2 men. And for me ok becouse roman coorts have the best armour protection and shield like hoplites
2 Test) 1 cohort (200 men) VS 1 velites unit
after shot all javelins cohort lose 9 men. Maybe a little too many losses for my taste, considering they have the best almost the best protection, but not so exaggerated after all. I prefer if they lose max 5 men but not a big problem.
3 Test) same cohort (200 men) VS 1 roman slingers unit
after shot all rocks cohort lose 50 men!!
You say "They can obliterate anything armour-less but can't do anything against those who have good shields"
so I think there is something wrong.
I think the actual damage of arrows and light javelins is ok.
Slingers seems just ignore armours and shields
Hope you can fix this.
Thank you
