every thing fights at the SAME TIME!
Tribal Wars 1 has the same battle system. xP
If everything fought at once, it would be total chaos (though, I suppose that is the definition of war). Remember, back in simpler times, they would all line up and take turns shooting at each other.
In all seriousness though, it makes the game more balanced. If everything fought at once the checks against troops would be meaningless. That would just mean you'd need to muster up the most offensive nuke you could (it would be 100% axemen or zerkers) and nothing could stop them. There would be no checks in place to stop them slaughtering the other army.
We need swords to keep the axes and zerkers at bay. We need archers and cats to take out the MA's. We need spears to stop the stampede of LC. We need rams to bring down the walls. Everything has their purpose.
Not to mention, the video was just a breakdown of how things get calculated. I'm sure it's very chaotic on the battlefield.
