One thing is clearly so stupid when I think about this...
Like, has Luffy's battle IQ decreased so significantly that he wasted his trump card (G5) on fodder MMA monsters instead of keeping his energy for the real threat? Like, I get that G5 was used to catch all the falling giants and to draw how large Dragon Loki really is but at that point, reverting back to a weaker gear, like G2, G3 or even G4, to beat up Sommers would be the logical conclusion to save up power. Yet he spammed his awakening on meaningless things and, surprise, surprise, quickly got turned into an old guy after having a clash with Imunko.
Does it even make sense at this point? I know Oda just likes to draw G5 but DUDE!!! Other gears already exist and Luffy perfectly masters them. It's like he completely forgot about it entirely.
