I think a lot of people are assuming that the level scaling option allows them to turn level scaling off entirely and go crush level 5 enemies from near the start of the game with level 50 characters.
It doesn't, it's an option for how far below the scaling will allow enemies to get. The lowest they'll normally be, with the lightest scaling option, is four levels below you, so if you're level 50 you'll be against level 46 enemies.
And for almost everyone that's going to be fine, because being four levels above enemies in Odyssey is a huge difference, especially later in the game when you've got all the abilities and equipment that you want and have started dumping ability points into mastery levels. The only reason to completely remove scaling would be to effortlessly crush low-level enemies whose strongest attacks won't even cause your health bar to move.
Wait, there's an option to make level scaling even more intense.
Yep, although enemies at the same level as your character isn't all that unusual anyway.
I guess turning on level scaling would allow you to pretty much zip through the story without com8ng up on level walled areas. I might dive back in and finally.finish it.
I expect the level requirements for quests to stay the same. So if you turn level scaling to the minimum, you'd still need to be level 30 to start a quest that required you to be level 30, you'd just be facing weaker enemies up to that point and probably getting less XP.
Wait, theres no, no sacaling option?
Meh. the very light version doesnt even sound that fun.
Four levels is quite a gap, especially early on. If there was the option to completely turn off level scaling, players who used it thinking it would be better that way could spend a lot of time smashing low-level enemies instantly, receiving junk loot and XP and maybe struggling to progress through the game.
For the people who enjoy playing as an overlevelled character, they'll get a lot of the same enjoyment from just that four level gap (plus the built-in player advantages of gear and abilities). For anyone looking for further challengeless encounters, there's always the arena where bigger gaps are possible (and inevitably result in enemies getting hopelessly stomped).
