To start good in the game you need to focus in one team only, i like droid team so i started with droids, hk-47 (arena) as leader, ig-88(arena), ig-86(galactic war), jawa engineer (guild shipments), chief nebit (arena)
but still farm other characters in other stores, like in the cantina battles the best to farm first is qui-gon jinn
if you found a guild that already clear raids fast i suggest farming the new meta of siths darth maul (guild shipment and fleet store) as leader, darth sidious (arena), savage opress (arena), Palpatine (event after getting rebels), count dooku (hardnodes and cantina)
to farm emperor palpatine it's better to use a rebel team with jyn erso(guild shipments)/wedge Antilles (cantina)/admiral ackbar (arena/ships event/fleet store)/lando calrissian (cantina) as leaders by that order of preference, using stormtrooper han (arena), princess leia(arena), chirrut imwe (fleet store, if not using ackbar), biggs darklighter (galactic war preferable is to use biggs and wedge together even if wedge isn't a leader), wedge antilles (cantina) if not used as leader, lando calrissian (cantina) if not used as leader, both the cantina characters are hard to get shards but they are overpowered i suggest farming wedge first then lando
