Why can boss fights be started while first-timers are watching the cutscene?

[Iagainsti]

Garuda windows are limited. When I was light farming my nexus I sometimes went 3 days without seeing a garuda window. That lost 40 minutes of a garuda window means it has to be made up in other instances which take much longer. Losing 40 minutes of garuda adds hours to light farming other content.

Do you at least understand why your parties get frustrated when you make them wait while you watch the cutscene for the 1000th time?

Exactly^ Anything to speed up the grind, please and Thank you.
