It just occurred to me that "training takes more time and commitment than fighting multiple legions of hell" is kinda stupid. Missions aren't really supposed to be something breezed through in 15 minutes, unless they're appropriately minor.
Honestly I think training taking more time then missions kinda makes sense. Most the missions we've been on so far, from the start of the quest until now, have lasted less then an hour.
Invasion of New York:
We got dropped off near one of the barricades, fought our way towards it, cleared out the enemies, and then repeated for the remaining barricades. The longest part of this mission, aside from the ride out there, was probably running from one barricade to another.
Graveyard Investigation:
Honestly I'd be surprised if this lasted more then half an hour. We pretty much walked around for a couple minutes, ran into some zombies, traced them back to the mausoleum, had a single battle, and that was it.
Laboratory Defense:
Most of this mission happened in a matter of
minutes. About the longest things were us quickly searching the office, probably five minutes given what else was going on, and the ten minute wait while Team GEAR restocked before raiding the Nightmare Nest.
Heaven Vacation:
Okay this did take
days but it wasn't really a mission.
Operation Starborn:
Once again it was the
waiting that took the longest. We flattened the first wave in under a minute, waited five minutes to talk, perhaps two minutes after that the second wave showed up, we flattered the second wave in under a minute and Sixth Heaven took about another minute.
So all told that is all of ten minutes from start to finish. Though we may have spent longer between then we leaving.
Operation Soul Collector:
We explicitly spent
five hours flying here:
"So what you up to, kid?" James' voice breaks the easy silence roughly five hours into the trip after you left the Messengers in the distance.
While the mission itself took, going by Nepgear's Health gains, took the following:
Entrance -> Silver Hero Defeated: 3 Turns = 30 seconds
SHD -> Radiances Battle: 4 Turns = 40 seconds
Radiances Battle: 5 Turns = 50 seconds
RB -> Grey Champion: 2 minutes in text
Grey Champion Battle: 5 Turns = 50 seconds
GCB -> White Soul: 12 Turns = 120 seconds
White Soul Battle: 8 Turns = 80 seconds
Juggernaut Drive Battle: 4 Turns = 40 seconds
Total: 30 + 40 + 50 + 120 + 50 + 120 + 80 + 40 = 530 seconds = 8.8 minutes
Even if we assume we spent
three times that long outside of combat the whole mission only takes up just over half an hour.
TL ; DR - Missions are
fast. The real issue is the travel times since they can take place over vast areas or even on entirely different worlds.
