The Argent Crusade knowing =/= SI:7 knowing. Plus, how much does the Argent Crusade knows about the Dreadlord’s capability to infiltrate and kidnap people? Enough to accurately anticipate and prevent any possibility of it?
…I don’t know about you, but I didn’t see any sign that Sylvanas hid enough Blight in the capital city ruins above ground to just blight everything. Only the regular amount of blight that is kept in that area. Nor did I see any Blight containers below ground set to detonate the last few times I did the scenario. So I remain skeptical.
If you track that the commander’s orders to give particular guards a night off come from another higher up, it probably wouldn’t make the difference you imagine it to make. Heck, with that in mind, I’d speculate that Shaw perhaps wanted to make sure the guards who needed to be off-duty were specifically off-duty. Sending it down the chain indirectly might result in the orders being garbled somewhat and getting lost in translation. Plus, it might’ve been just faster to tell them directly than to tell the boss of their boss to tell their boss to tell them that they got the night off. It wouldn’t have been a big deal with the Horde investigators were dealt with before this point, as was planned.
That’d be a fair mistake. But hardly anything worth forcing him to resign over and handing the job to a less experienced manager. In the grand scheme of thing, it’s positively minuscule.
Look, what this comes down to is whether the man is guilty of actual chronic incompetence or simply bad luck. For instance, I don’t think being kidnapped and replaced by an extraterrestrial shapeshifting demon that majored in political intrigue at Nathreza University qualifies as chronic incompetence. Nor being duped by a single counter-intelligence scheme, having your subordinates miss the hidden trap juryrigged on short notice, or even just appearing in person to get a few guards out of the way with no questions asked by them.
What should be considered is whether these “blunders” outweigh the man’s life of experience and service in the job. Which involves helping to deal with the Defias, keeping tabs on the Scourge, scouting out Nathanos’ location in the plaguelands, assigning agents to accompany Varian’s mission to (almost) assassinate Moira, and helping to deal with the Twilight Hammer cult’s forces personally on several occasions. Hell, he found out the Legion’s trap and almost warned the fleets, at which point the Legion had to directly intervene to stop him.
All this tallied up against, what four bugbears on his record that are of questionable import? Seems like a stunning record to me, and making him resign without seeing if he can improve upon himself after these setbacks would be tossing out the baby along with the bathwater. Because you’ll be down one veteran spymaster until you get one with the chops to replace him.
