Chaos Packs : Voucher sale, General Sale or Market?

I have a big question to solve: Buy in the second phase of Presale or wait for General sale?

It's way harder than it should be.

One the one side I can see those vouchers for almost $3 each so 100 card in presale could be 175 in general sale.

On the other side if things sell out too quickly I could miss out on valuable airdrops.

I missed Yodin and the Llama last time around do I want to risk losing out again?

To make matters worse I don't know how many packs I'll need for the "Guaranteed Airdrop". I'm hoping its 50ish for the Epic's and 100ish for the Legendary. The documentation only says "will vary depending on the rarity of the card".

It doesn't help that both SPS and DEC have tanked so my nest egg to buy cards has dwindled.

Then there is the follow up conundrum. Buy packs or cherry pick and just buy the individual cards. The Chaos legion cards have fallen off considerably from their initial price and could fall even further once the next batch of cards gets released and there is a glut of them on the market.

Sure there is every likelihood that they will rebound once Chaos packs are gone but how long will that take.

Decisions Decisions...

So frustrating.
