As much as I dislike the ridiculous hitpoint bloat of higher level enemies, level scaling is even worse. I have it deactivated and do not intend to ever activate it, because it's shit.Might still be able to use the level boost mode they added when they introduced new areas in dlcs. It should kick you up to around lv45 which is about max game level, then check the game's difficulty settings for something that scales all the enemies and npcs up to your level so that the world becomes static and the power differences between enemies have to do with the type of enemy rather than the stat-buffing level randomly attributed to the area they spawned in.
Also I'd rather unlock new skills gradually as I progress through the game than get them all at once.
