Ships Composition Advice

Put Ahsoka into your starting squad. The ability to break a taunt (or other problematic buff) on demand is really important. Sure, 5s can do it, but you need a target lock first, and if the taunt is protecting someone who has been target locked, you're out of luck. I think I'd swap the Soldier for Ahsoka, personally--At least in my experience, he didn't seem to assist often enough to be up there over a debuffer.

Also, you might consider swapping Home One for Endurance, depending on how invested you are with Mace. Endurance is a STRONG fleet ship.

I'm running the same squad practically and made it to 4th on my server earlier this week but dropped down to 18th with
Home One
JC
Fives
Wedge
Biggs
Ashoka

With
Geonosion Soldier
Resistance X Wing
First Order Tie Fighter
On reserve.

I try to avoid Mace squads. I either get timed out or I get crushed.especially if they have Vader's tie fighter.
