The whole recollection mechanic is kind of broken in the Underworld in my opinion. It's literally the case of "your weapon is as powerful as it needs to be because it's powered by your thoughts". I also think Eugeo is a little bit overhyped in the anime. Okay, he beat Bercoli, which was impressive. But I don't think he's miles above anyone else on the crew. Maybe my prejudices are coming into play here as I never really bonded with that character for whatever reason. Maybe because he kept coming back in some fashion so many times after dying. And how Kirito (at times) almost appeared to care for him more than his real friends who we see are working their asses off trying to find and help him. The power scaling thing is silly though. It's why we liked the first Asuna v Yukki fight. Just a simple duel to determine who's the best swordsman/woman. They should do more of those, just for fun. Maybe Asuna logs in and Klein is dueling Liz for a discount in her shop of something silly. 😅
Well, in a game videogame setting Suna vs Railgun might just be a ție or even a clutch Suna win, but in reality Misaka anihilate Asunas back side in 1 shot
