But that's just the thing, he's not weaker than Loli. The feats objectively say otherwise, as does his mana. There was literally a statement where he was said to be a single step below Hwan, and this is from an official translation, not from the most recent, tentatively translated chapter.
Unless Lolikiano is somewhere between these steps (which would leave a giant hole in logic), Han must be superior to her somehow. Perhaps she's simply more skilled or experienced than he. But in terms of raw magical power, he's been stated to have magic power that exceeds her. Mana isn't simply power all applied in one shot, otherwise Yoowha would be superior to Han for taking his mana in one shot. At least her durability vs his AP. But she's not. They're roughly equal in the majority of their stats. As his regular attacks were plenty able to harm her.
His raw magic power is, often times, what grants him his resistance to power nullification. Not that he has to be stronger, but his magic power has to be sufficient enough to resist what's being produced. You yourself compared it to a d*** measuring competition previously. Showing that indeed, magical power, and AP, do indeed rely on mana in the case of mages.
Considering that a good deal of the company doesn't even share the AP of Han, many of them would be one shot. And considering the statement of being a step below Hwan, and the numerous powerups since then, he should be able to one shot a vast majority of the company's members.
But, once again, this doesn't take away from the argument presented earlier. With regards to the mind manipulation, and Han literally being made to fight armies by himself. I think to disregard the comparison between Han and Hwan, Han's enormous growth since last arc, and compare that to what Hwan as shown would be incorrect. We in fact, have to compare to Hwan for he is the only one who has fought against the company aside from Loli and her druid. But he is the only one who fought against the President. And Han should be scaling to all of them, just as they derive their scaling from being somewhere vaguely above him. That vaguely being not all that high considering he's one step below Hwan.
The reference for him being just one level below Hwan is Season four, episode 5. Well before some of the numerous boons of the arc.
