I used to run Diala in my force user list:
Luke
Leia
Diala
Davith
Gideon
3PO
R2D2
Balance of the Force (I think)
Heroic Effort.
But Obi Wan is also 7 points, but hits harder and has more health. And has a nice control ability for locking down objectives.
Is there a reason I should ever consider Diala anymore instead of Obi Wan?
