If you're using Chopper outside of Phoenix then yes, omega his basic. Hera is not the damage dealer in Phoenix, so unless you have 5 omegas sitting around and have already Omega'd everything else on the squad, no I wouldn't Omega her basic.
For example, compare Hera's basic to say Zeb or Ezra, or a few outside examples of Ahsoka's basic and FOX's special:
+15% damage for 5 omegas (3-5 days of farming)
Vs
- 40 to 80% double attack chance (+100% damage essentially)
- +30% damage against debuffed enemies
- +15 damage AND +10% heal (Ahsoka)
- +30% damage overall (FOX)
Those are all worth 5 omegas. Personally I think +15% damage should only be 3 omegas as at earlier tiers the same is accomplished with combos of colored ability mats only (1 run on an ability mat challenge).
