Can someone explain what this x20 is?
In 12version of the game for example oplites have
Hit points :56
Armour:1
Damage :18
When units in workshop upgraded armour increased by 1 for every upgrade and goes to 1+3=4 maximum(3 level upgrades available) and damage increased by 1 for every upgrade and goes to 18+3=21 maximum.
In 13 version these numbers are starting increased *20
Hit points :1120
Armour:20
Damage :360
When units in workshop upgraded armour and damage increased by 1 for every upgrade and propably there is no limit cause as it said "Unit improvement levels in the Workshop are no longer limited".
In short, they changed the upgrade ratios so that each upgrade has a smaller impact.
