Enemies into acquaintances is much, much, stronger than allies into minions. I mean, once someone is devoid of all problematic intimacies, you can often just pay them.
And if they have some kind of problem with being brainwashed, you can just scalpel away that problem.
You explicitly said the opposite, actually.
As for Memory-Reweaving Discipline and the like, they can be resisted in various ways. Including just spending willpower. This prevents people from even wanting to try.
I mean, if your argument is that enemies to acquaintances is stronger than acquaintances to allies... Well memory Reweaving does enemies to allies (one use removes the intimacy, another creates it). (This is an area where I feel like I'm just *missing* some rule or something because I feel like we have such a contrary read of the effect?)
And they can both be resisted, it's just one requires social defence and the other requires combat defence (and also because I accept the keyword defence the sword can *also* be blocked by a lot of social charms like righteous lion defence)
Finally, I don't agree removing an intimacy automatically means enemies to acquaintances? Like, example scenario:
I'm a black court vampire. I'm fighting Harry Dresden to the death because I'm trying to kill molly and he doesn't want that to happen.
So first I remove his intimacy for Molly (which means I *could* have killed him). Then I remove his heroism intimacy (which means I could have killed him) then I remove his intimacy towards the white council so that he isn't duty bound to fight me (which means I could have killed him).
Well that still might not be enough to end the fight because even if he has no emotional attachment to these intimacies we are still fighting to the death and he remembers me removing these intimacies.
At that point I could have killed him several times over just to create the same effect as a single use of Memory Reweaving Discipline.
And sure, that's an extreme example, but I think it does a good job of showing why I don't think this weapon is nearly as powerful as you think it is?
(It is, of course, useful. Removing these intimacies makes it a lot easier *to* stop the fight after all. And there is going to be a period after the fight but before your opponent regains their intimacies where they are a prime candidate for flipping. And not everyone will be able to muster the energy to regain these intimacies [though I imagine most player characters will]).

I feel there is a miscommunication here.
I don't consider that the opposite? It removes your desire to regan it because otherwise overcoming the effect is trivial, but you can explicitly surprised that with one WP so that characters can force themselves to reconnect with what they once loved. Also any character should have should have a support network working to help them reconnect amd heal the damage.

Like in my mind the primary use for this weapon is to give the wielder a brief window (1-3 weeks) during which they lack the ideological cause which drives their conflict with you. Sometimes you'll get lucky and the opponent won't spend the effort to regain that intimacy, but I'm assuming any Heroic opponents will do so.
