You're welcome! Not sure about the wisdom part, haha, but I'll agree that I've accumulated quite a bit of experience with this game. Yeah, that's a tough one. Some of the airdrop cards will apparently not be Legendaries, and will thus require fewer packs for airdrop-eligibility. On the other hand, you'll need more than just one airdrop card to level them up to an adequate level. To max out cards for use in Silver League, 3x Legendaries are required (for Lvl 2), and 10x Epics are needed (for Lvl 3).
So if this were to be done with airdrop cards alone, that would require 1050 packs this time around, more than $4k. My point being, some gaps will probably have to be filled with singles anyways. Maybe this will make it a bit easier to just settle on a number of packs to buy and be at peace with it.
It is damn fun to hunt high-level golds though. [..] I have a 2 gold summoners and a gold epic, and they'll be great over time, but I want one notch up,
Opening packs is so much fun that it's not even possible to understand it, hahaha! But yeah, that's some great pulls! I actually got my first two Gold Foil Legendaries with Chaos Legion – Never owned one before that. Mainly because back when I was tearing open all those Beta packs, I didn't understand/care to comprehend the concept of Potions, so I just opened without. What a calamity it turned out to be. Just make sure to always always always have enough Potions when opening :D
