I really hope they don't ruin it by making the MC the only competent character. I don't want this to be a self jerk story where everyone starts stroking the MC. Hopefully the other characters start getting some respect and development.
We need to see how the manga will deal with the later events since it fixes many things compared to LN/WN. IIRC after the reverse siphon idea of all things the WN/LN kinda turns into "SASUGA WERNER-SAMA" wank, but it gets better as it gets further as we will get some intrigues or battles where the writer isn't able to waste most of the chapter to explain how lower ranking aristocrats have lower political power/authority than the higher ranking ones. Or some other obvious concepts that try to make MC smarter than he is, when we already saw him being smart in his actions before.
It also allows other characters to expand upon his ideas or even use certain items that Werner orders in a surprising way. That said the OG story is still much better than your average isekai story and it keeps true to the title.
Also the best part about this series is that the biggest fangirls of MC are old men in power who, like the Crown Prince, want to keep him around by any means necessary, quite often allowing him to do seemingly crazy stuff or manipulating current political situation, knowing that it will make the war much easier down the line.
But yeah, the biggest problematic element of the series is the RPG mechanics, an by that I mean mostly the monster loot system. Like some things can only be made from X part of Y monster, when the world seems like to be so familiar to our own that it should have been possible to use natural materials to replace it. That said Werner isn't a walking encyclopedia of everything ever, so I can turn a blind eye to such fragments.
