Mega Card Pack wouldn't make much sense - we already have a Card pack, and there's too many treasure cards for you to get the one you want. Mega Reagent Pack might be an idea, but, like the card pack, there's too many different variables for it to be that useful. I mean, do you use the Eye of Bartleby or Reagent packs much?
The pet pack... No, just no. It would be so very unfair to those who save up and struggle to buy fancy, spiffy pets or to hatch with people to get hold of specific rare pets, if you can get a Sea Dragon or Friendly Dragon from a 2k crown pack. Or people would throw up a fuss because they get Unicorns and Piggles from it.
