Alright, I finally had time to pull together a full year worth of packs data and it's actually worse than I thought. I did something like 2-20-2022 -> 2-20-2023 or something.
1 year of packs = 26260 antique tokens (1270$)
415 tokens per event/4980 per year (240$ free)
Per month, it requires an average of 2188 antique tokens to buy every pack item on average.
Average buying power: 18.9% - roughly one T12 BP would mean basically if you are aiming for high end stuff only, in a month you can only get one T12 BP out of all the packs that drop.
But of course, T13 will change things. Currently it is assumed that T13 will be 400 antique tokens. You will still be able to get 1 T13 BP from the collective packs that drop each month, there will just be far less leftover points to save for anything else. There's a chance the mid tier BPs could go higher range too, which may raise antique token costs further.
Accounting only for T13 BPs, the cost in Antique tokens per year to buy everything increases by 2850, or just under 7 more events worth of tokens. This increases the yearly total antique tokens to 29110 if the typical mid tier secondary pack BP stays around T5-T8. The monthly average increases by 237 , to a total of 2425 anttique tokens.
With this new value, your average buying power per event is now 17.1%
I feel that with these numbers, I have shown that King's Caprice really can use a boost. At the rate packs come out, my unserious suggestion they just double tokens seems even less impactful. There's likely to be 2-3+ packs per month already, and going from one T12 to 2 T12s while still leaving all secondary BPS and remaining T12s still leaves a huge amount of never obtainable stuff.
