This guide lacks a bit in fleet information.
I use this approach:
https://forums.galaxy-of-heroes.starwars.ea.com/discussion/81985/mostly-adaptive-fleet-building-guide
=> Ackbar Lead, (Biggs/Sun Fac/Geonosian Soldier/Jedi Consular/Ahsoka | Wedge/Boba/Maul)
You can't have Bobas Ship right from the start, it costs 80 shards.
One can buy like 4 shards a day, so 20 days until it is ready.
Therefore, I go:
- (after Boba/QGJ 7 stars, and after having farmed my mods:) Ahsoka in Cantina Store
- Ahsoka in the hard nodes
- Jedi Consular in hard nodes
- Sun Fac in Guild Store (no Rey for me)
- GS in Cantina battle (after Lando is 7star)
- Ships in GW store (Jedi's, Ahsoka's, Biggs', Wedges Ship), (after Biggs is 7stars)
- Wedge in Fleet store (can be farmed with lvl60!) and Slave I (Bobas ship).
- If your Fleet Rank is good enough, also Sun Facs, Ahsokas, Jedi Consulars, GS, Biggs, Wedges Ship
- Ackbar in Arena Store (after STH is 7star, but before IG88)
Note, at lvl 62 for the Ackbar Ship challenge you need 6 ships with 2 stars.
As a strategy for the fights, I focus the enemies Biggs ship first, because it gets a taunt anyways in round 3 or so, so it is good if already weakened.
