Seduce Units Budget

[Sire of Suns]

I'm sure others have noticed and discussed this (though not much discussion from what I can find in the forums here), but the Seduce Units budget seems to be... Not great.

The cost to seduce units is partially tied into how much seductive influence you have with the faction (and some factions are immune), but even then there are some units that have a seduction cost that reminds me of frustrating and unethical micro-transactions in predatory games. A unit may need 1050 to be seduced, but your budget is 2000, so if all of the opposing units are 1050, you can still only get one. Increasing your seductive influence might bring that down to 1000, hooray now you can actually seduce TWO whole units! Of bad quality.
Or perhaps one unit worth 2200, or some other weird cost that makes trying to seduce units and choosing what to seduce a frustrating chore.
Then your budget seems to fluctuate, and it still isn't clear to me what determines the budget. Is it devotion to Slaanesh in the army? Slaanesh army authority? Slaaneshi influence? Slaanesh corruption? Who knows, I certainly don't.

Then, the ai of course seems to often have a much larger budget than the player, and seems to always be able to seduce whatever units they wish. This might be due to the ai not being able to vassalize the player, and so they have max seductive influence with which to reduce the cost, but even as a player when I reach that point and don't vassalize, I never seem to have the budget and discounts to get the same kinds and number of units the ai does.
So, of course the ai will effectively auto-delete key portions of your army, while the player can never do the same. Having to fight against the Slaanesh ai while spamming cheese armies isn't really fun, and playing as Slaaneshi factions and not being able to effectively or enjoyably use the same mechanic is frustrating.

Mostly, I've found the mechanic to be a useful way to ensure that a decisive defeat for minor settlements actually kills something in auto resolve, rather than spreading out the damage so that nothing actually dies in the ai army.

Streamlining and clarifying the mechanic a bit more would make it more enjoyable, I think, without making it op for the player and helping the player to alleviate frustration by at least understanding how the ai is able to do what it does with the same mechanic.
