The timing for it was just clumsy.
HSR always sucked at when to exposit backstory, down to Belobog where we awkward have to watch Cocolia echoes show key pieces of her backstory right as we're climbing up to her boss fight.
It's a failure on the writer's part to organically put those in the plot.
Penacony is kind of masked because Sunday was a very patient antagonist who explained everything before his battle trying to convince you, but same problem.
And Amphoreus tried to do that again, except Lygus is a retard and this time there were multiple characters that needed to be infodumped alongside the boss of the patch.
