You see, there could be an argument for Kyros sending the most incompetent people to do his bidding, and they certainly seem incompetent enough in the game but they aren't painted as incompetent in the pre-game which makes me think they weren't intended to be so.
Ashe is portrayed as the last hold out Archon, when everyone else was bending to Kyros' will Ashe somehow resisted him for a long campaign, presumably heavily outnumbered and far away from friendly supply lines. Ashe gave me the impression of a fantasy Hannibal, never losing a battle, sure, but sometimes screwed over by the strategic situation. And he is The Archon of War, sure that must mean something, being the go to henchman for large scale armed conflict, yet (to take an early example) he apparently doesn't even inspire enough loyalty (or have enough forethought) to have his siege mages turn up to the siege which is at the moment the only conflict in the region.
The Archon of Secrets was the most disappointing for me because he seemed so epic in my conquest run. The two of us sat down and hatched a plan to bring the downfall of an entire order of mages without shedding a drop of blood. That's genius, and it demonstrates an ability to cooperate with others that just doesn't seem to be in the game. And honestly, Secret's ability to convert enemies could have been a lot cooler, imagine storming the walls and suddenly one of your enemies turns around and stabs their friend in the back because they were a spy for the Scarlet Chorus. Instead Secret's willingness to convert enemies is a major campaign weakness (and I still can't get over the fact that they wanted to kill the single useful prisoner they had before I intervened, and yeah maybe they didn't want the camps location revealed, but do you know what would have been easier than all the bull they pulled? Just not asking me to help) because apparently Secrets is useless at making conversion stick, despite the fact that he's got Siren, the Archon of mind control sitting around twiddling her thumbs in camp.
In this case for me the problem is that the show doesn't match the tell. And while there could be deep interesting reasons for this the more likely explanation is that the writers weren't capable of showing what they wanted to tell.
