If this is how this timeline is going to progress from here on out - stupid Romans facing perfect enemies who only lose because of things out of their control - then I may need to re-evaluate my Patreon status. If I want to read about dumb Byzantines getting their asses kicked by awesome leadership I'll just re-read Jonathan Harris rather than spend my money on this.
Jesus, ease off mate. First off, no one is forcing you to spend anything on this. It's literally posted in its entirety on a free forum. And giving a voluntary contribution doesn't entitle you to twist the story in a direction more to your liking.
Secondly, I think you are vastly exaggerating. Sure, the Romans haven't been blessed by military genius in recent decades. But at the same time, you could complain that the Germans are lead by a buffoon of an Emperor, who is stubbornly leading his house and nation into ruin when all the rest of Europe can see it for the folly it is. All the while the Romans have an administrative genius at the helm, who comes up with stuff like progressive tax brackets to field twice the number of soldiers as all his opponents combined on a much smaller population basis. I don't really see how you can talk of "dumb Byzantines" in this scenario.
