I did some changes in the OP:
Removed the part about ally coins for tourneys and added a block "Zeta Challenge":
Zeta Challenge: (hard, probably need lvl 80+ but start preparing earlier):
Aim for a 5th light side ship for 5* Home1-challenge (Ackbar's capital ship)
- If you choose Rex, begin to farm his ship ealier, it is a slow farm. Farm Rex in guild store.
- If you choose Clone Sgt P1, occasionally farm his shards in hard nodes.
- you can also use both (2 reinforcements allowed)
Aim for a 5th dark side ship:
- Farm TFP's ship for the 5th dark side
Aim for 8x 5* ships (Biggs, Wedge, JC, Ahsoka, Sun Fac, GS, Slave 1, Scimitar; TFP if your Slave/Scimitar farms are too slow and you think you can finish the challenge earlier)
- Farm Tarkin in Arena Store after IG88 is maxed.
