Twinsies, yay.
Ahem, well for me it's just a matter of getting rid of it altogether, none of it makes sense. So Mel is supposed to have taken on two commandments who are in the 50K PL range?The only way I can make sense of it is perhaps Dologlox aren't original demons, if we think about it they didn't even use the darkness power which is common to all demons, while Mel did so that might have given him an edge. Which begs the question why didn't Dologlox use the darkness? Maybe they can't, even though Glox obviously has a demon mark.I don't know, it makes no sense.
Not just that but Escanor is supposed to have weakened them before that, while he was just 28800 in PL? Granted he used Rhitta's release, so let's say he doubled his power at that moment. It still wouldn't explain everything. And then frigging Arthur having 40K PL, but he struggled against a gray demon. It's true that he hasn't unlocked his magical ability yet, but I feel it was too premature to reveal the truth about his PL.
Since pretty much everything goes back to DB apparently, while in DBZ the scouters were introduced and they showed the power levels of the characters, they slowly got rid off since the fighters from Earth could hide their power level/ki. So that imo is what ultimately should happen, or like you say destroy the power eyes,but even then Merlin could sense Escanor's PL, and pretty much everyone can sense the power of someone, but it takes the power eyes to get the detailed values.
