This is a Noob question but serious one.
Can you use play legacy as normal pandemic for a few games before opening all the legacy components?
My wife and l played about 15 games without using the legacy parts.
Tried 5 characters. And had loads of fun trying new things out.
Best combo we found for our game set up was the Medic and dispatcher.
Our game set up was..
We played 1 character each and we started with 4 player cards each.
5 funded cards in player deck.
And of course the epidemic cards.
We set our own victory conditions as eradicate all four diseases. Which we only managed to do with these two characters. Medic and dispatcher.
We liked this challenge a lot and many hours of fun doing it. It prepared us well for the legacy game which we have won all 5 games so far. A bit of luck helps too.
