>>106733941They should not do that because it is wrong, and the final story boss maxes out at level 65 anyways. Characters can be way underleveled as long as GFs aren't anyways, base stats are not that big.
If you have a 15/10/10 party normal enemies will all be level 9 or 13. Even with a 40/20/20 party they will be 21 or 31. (boss strength significantly varying from attempt to attempt is maybe the actual worst thing about the level scaling, Adel could have either 26,000 or 36,000 HP in that scenario) The whole purpose of the system is so that when your 3 underleveled characters get stuck in a party together for an extended period they don't get their shit destroyed while the cool kids team casually tramples everything and make you need to reload a 10 hour old save that probably doesn't exist.
