Today I have the first big war in my game and have faced many issues - maybe not bugs but annoying things.
1st and main - the concept of Grouping units is completely broken. When you have group of soldiers, it should be a set of soldiers who can die and combat and the strength of group will lower. Let's remember Master of Magic - combined units have great attack (Human Halberdiers zomg) - but only when full strength. When the group consists of last wounded soldier it should NOT fight as fully rested battallion.
Now in EWoM the unit fight with full attack and defence until death. This broke all war concept completely.
Okay, its maybe feature. But why the lost soldiers are not revived when unit have healed and rested? I have Veteran unit that lost 3/4 of stack and then they fight alone - see screnshot:
If I heal unit the lost members should revive I think.
Next. I've cast Confusion spell on the Troll unit of my enemy - and his attack downed to negative number - really, Troll missed all attacks to the death:
And the last for now - AI have negative credits and flooded me with armies:
It's not a big problem but I think something strange with Empire races. They always have dominated the world, they destroys Kingdom races one by one. In all of my games when all Kingdom races have ~50 strength Empire have ~300. I can defend and even attack Empire but my allies not - and they fall one by one. I think this should be justified.
