I, for one, fully agree with Eric.

Also, as a personal note, my group has rarely come up with narrative stories for battles. We play way too often ot try to justify every single fight. Most times, if we cared to, it was as simple as "We saw one another and said "**** those guys!"" Hell, Dwarves are super easy to justify cause they literally have an army rule for how much of a reason the army has to be there to fight the enemy.

And this is coming from a group that is hugely role-play and narrative oriented.
