Why doesn't the MSQ have quests where you participate in large open battles?

Remember the Stormblood benchmark trailer, where you had many Alliance warriors fighting against Garlemald forces in the Fringes?

But in the actual Stormblood campaign, nothing remotely happens like that. The capturing of the tower in the Fringes involves half a dozen to a dozen Resistance troops at most. In Doma, a dozen Doman soldiers, a dozen Xaela tribesmen, and one ship with a half dozen pirates on board somehow manage to successfully assault and capture an entire capital city occupied by a provincial army.


Remember the Endwalker benchmark trailer, where you had an Alliance army fighting in Garlemald, with the different faction leaders charging in with their forces?

But in the actual Endwalker campaign, you have a solo instance where there are a dozen people or so trudging through the snow to fight a dozen Garleans, and then another solo instances where groups of half a dozen people are spread out across different screens fighting monsters, making for an extremely low density battlefield, even with the magitek squad shows up.


Remember the Dawntrail trailer advertising an airship invasion?

But in the actual campaign, the battle of Tulliyolal is just a dozen plastic robots waltzing through the streets and then a half dozen dragons show up, and then a dozen cowboys + Estinien fight a few more robots in the desert.

Why does FF14 have an aversion to showing large scale battles? Not even RTS game large, just benchmark trailer large, which the game is capable of?
