it took this dude 30 episodes to figure out that maybe kicking things is better than breaking his fingers one by onebreh went from breaking his hand every time he fights to being able to use his quirk pretty naturally.
Now with the new stuff he still at least has to work to master it, its not an overnight powerup
on top of that, you got side characters who all make real changes and improvements in a fraction of the time showing clearly that the writer has no idea what the fukk he's doing with deku
and if you're caught up, deku is really full of shyt. dude gets powerups literally falling into his lap.... shyt worse than when ichigo found out he was part everything
