Ever since I first read it, I have loved Avoiding the Truth Technique....in theory.
After I learned a bit more about how social combat and stunting works, however, I realized something: it does literally nothing. You have to stunt your truth-that-is-to-be-seen-as-a-lie to justify using the Charm. But if you just roll a Manipulation check and stunt your social attack as, "I tell him the truth, but in such a way that it sounds preposterous and he thinks I'm either lying or utterly addled, so will dismiss what I'm saying as wholly fictitious," you get the same effect, but without spending motes and possibly regaining some!
Avoiding the Truth Technique doesn't even add dice to the roll, not that it would be all that great if it did, because excellencies do that.
So, this is where digging into the history is fun: 1e Avoiding the Truth Technique did
add bonus success. It was actually really versatile within the range of "convincing people you were lying," since it could add to Presence, Socialize, or Bureaucracy (back before social influence had any level of codification).
Then 2e comes along and gives everyone generic Excellencies. Now Avoiding the Truth Technique just becomes UMI (maybe? the text is unclear) to convince someone you're lying. It also moves to Larceny, for some reason. Of course, 2e Sidereals didn't really take into the account that now we do
have rolls for social influence/"attacks," so it ends up giving this cool concept the mechanical support of a two-legged stool. Glories of the Most High patched this issue generally by giving these Charms specified Willpower costs to resist, which gave Avoiding the Truth some teeth. 2.5 kept the increased Willpower cost, added back in the bonus successes, and also gave it some ability to interfere with truth-detection techniques. For a patch job on top of a patch job, I think it ended up pretty good.
In 3e, we'll be able to approach Avoiding the Truth Technique free from mechanical baggage, and just do a top-down execution of its really cool concept. I'm optimistic about this going well.
