Normally one could look at this and say that is doesn't make the game any easier, but after playing through OWB, having to fight enemies scaled to content with a level 45 character was an absolute pain. I haven't run the DLC at level 30 to see how it compares, but I'm assuming that the enemies aren't as powerful at 30 as 45. If this is the case, the Logan's Loophole trait will actually make the game easier since you'll still have a powerful player character, but the enemies you'll have to fight could be weaker than if you were max level.
My only other complaint with respect to this trait is that it takes up a spot for another trait, making it even less desirable in my mind. It really feels like it should be a completely separate option.
