InMediasRes --> It is clear this isn't a war between states or Emperors, as the fact that D3 is far better at his job than Theodor is at his is negated by the fact that Blucher is unbeatable and Laskaris is pretty dumb. If the fact that D3 is great mattered this war would have been won by now handily, but in this world tactics > strategy so Blucher carries the day.
Evilprodigy --> I've offered constructive criticism before about Iskander (the clearest example of an overpowered Sue in this timeline to date) and the fact that he was complete perfection detracted from the story as it was implausible. People agreed with me at the time. So don't act like I'm coming in cold here, I've voiced similar issues before only to have them fall on deaf ears. Our author agreed with me that a lack of characterization weakened Iskander, but instead of rectifying that he doubled down with conjuring another anti-Roman general who can do no wrong.
Mate, seriously. I don't know how you get that impression from the update. I loved it.
Blucher is a good general, and outclassed, not by pure tactics, but blessedly by strategy (one that I'm quite happy was the case) and the use of resources, logistics and the like. All things that show that Laskaris isn't dumb (dumb would be just launching full force into the enemies guns) but playing the game differently, by making it untenable to fight. If anything Blucher is a great general with awful orders and a terrible situation (much like the Roman people caught in the middle) but Laskaris is certainly if not a great general, a damn good one whose strategic situation is superior, and has the support of an Emperor whose letting him fight as he needs to.
The point is, the Romans are winning, not through some great avalanche, but by what they're the best at - Logistics, Planning, Diplomacy. It isn't a sexy charge to crush the enemy in one fell swoop, but this is a great victory.
In constrast, I can agree with it on Iskandar, he got to be rather uncharacterised and brilliant, but he wasn't the main character. Ibrahim isn't as great, but gets some more breaks IMO. But I think we're on the cusp of seeing the Romans explode into precisely what you want - a storming victory - in the East by letting Ibrahim isolate himself, and in the West by taking control of the Danube from the Germans, and restoring their frontier whilst having the initiative and bleeding their enemies.
Its classic defence-in-depth and whilst it isn't sexy, or pretty - it's brilliant nonetheless. I'd personally be disappointed if it became cartoonish, even if I want to see great Roman victories more often. But I just did, through Roman Strength rather than Hollywood Bravado.
