Agree with @Val_Galahadred it depends on where to use.
HPit, If you have JTR, team up with CLS, B8 and HS and you won't need a 2nd team.
HAAT:
CLS + HS for P1 (can solo P1)
JTR for P2 (won't solo it, but can do some dmg)
Ackbar team to solo P3 and P4.
TW
The team you mention: CLS (L), Leia, HS, Ezra
First, I need a tank for the 5th slot (can it be Kanan or Obi Wan)
Second, I would take out one attacker for a healer.
For TW, I would really suggest you take out Leia and put her into a Nute Lead Team, keep Kanan on a Phoenix squad, put Obi Wan as the tank and a good healer (ideally CHS) - that's the same team I would use in LSTB.
