and why unit formations are so thin for sake of width?

@@s.novozhilov1856 it has three main reasons. first of , the fact that the thin line provides maximum protection from missile damage by the enemy. and second reason is tactical , since you have a higher chance of forcing enemy units getting engaged in your melee. finally, the more space coverage is the strategical reason for why "thin" formations are preferred by top players.

Yes. we could finish off the cavalry battle here in that moment, while the enemy was concentrating on the melee on the other flank. the Nordic bow units in this battle , helped us , by being completely inactive for the majority of the battle, and then forcing their friends to route quickly.

@@Very_Bad_Bishop yes is about turning point or Rome 2?

@@s.novozhilov1856 The turning point XD I only play Attila MP.

The early harassment is the enemy's obvious plan. how successful will it be , is another question. it is not the only possible tactic in hands of the Huns though. as for defeating the Huns, you can mainly count on their weak melee cavalry and lack of slingers to pose serious ranged damage , their best try is to bring the mounted bow units , but then this simply reduces their budget for investing on other parts.
