Starting off with the mandatory observation that ship meta has been stale now for many months (I am looking at you, Negotiator and HT).
We have very few FO and resistance ships to pair with their respective capital ships. With people soon getting Finalizer and Holdo's capital ships to 7 star, it is important that CG releases 2-3 (1 pilot less) ships each for these factions soon.
This becomes very important for GAC given that some of us need 4 ship fleets to compete.
Also, to make the game mode popular, it would be good if some more (newer) ships are placed in arena, cantina and fleet stores.
Last but not the least, bring Jar Jar Binks into the game!
