I'm a begginner but i can buy 5 shards a day on this shipments, which character would you get first?

For Arena shipments, I recommend focusing on Darth Sidious first. He's the strongest from that group.

I researched a lot of threads when I first started playing and it seems the general consensus is:
Arena shipments: Darth Sidious
Cantina shipments: Old Daka, Boba Fett, Fives or Poe
Galactic War shipments: Luminara, Phasma, Poggle

I'm pretty sure that Sidious & Luminara are the 2 characters the majority of hardcore players unlock first
