my theory about this is those who like to upgrade power and defence are those that like to play for brawn but those who play with higher appitude and personality tend to play with brain (considering they dont have the power to fight them head on)
Aptitude helps you to get stronger.
Personality gives you more slots.
Because they have no in-battle effects, you might as well just not upgrade your Attack and Defense.
Besides, your team exists too.
I always go with 11PD1PA12AP12P
That way, you can pump up your PA very high after the ghost battles, you can talk Azma out of fighting with you (you can't win that battle), and have Luca on your team with the others (you are weak so you need as many teammates as you can get).
The only problem with this build is the prison break and ghost battles. However, with a little caution you should be able to overcome them. I'll go over the kind of caution you have to use in your first six battles. Griffin's advice will not suffice. [/badpun]
For example, in the Prison Break battle with a bowman and two bandits: (M=Bowman, B=Bandit)
M
B B
You have to place Griffin, Duvalier, and Rahel in the following positions:(G=Griffin, D=Duvalier, R=Rahel)
M
B B
G D
R
By doing this, Duvalier attracts the fire of the Bowman and a Bandit, helping Griffin survive.
This is the first tricky battle, as to avoid getting everyone killed you have to think everything through and get your positioning right. After that turn:
M
B B
G D
R
Duvalier has only 8 HP now, and one shot from the Bowman will kill him. Because of that, you always have to have two units between him and the Bowman. Griffin will have to take over tanking, and Duvalier healing, which means you have to keep the right bandit alive to block the bowman's fire.
M
B
G
R D
The Bandit and Bowman will attack Griffin, who will counterattack, leaving the Bandit with 16HP. Your goal is to let Griffin's counterattack kill the Bandit; that way you can let both Griffin and Duvalier survive (otherwise the bowman will kill one of the two)
M
B
G
D
R
The Bandit now has 9 HP. He will attack, lowering his HP to 3. The next turn do not attack with Griffin or Rahel. When the Bandit and Bowman attack, it will be your turn and the battlefield will look like this:
M
G
D
R
Griffin will need healing, so do not move him, keeping him there and healing him with Mind Shield as Rahel moves to keep the Bowman away from Duvalier.
M
R
G
D
From then on, it is a simple matter of surrounding the Bowman and killing him.

Despite the early rigors of an 11-1-12-12 build, the rewards are great. The stat that you put at 1 can be upgraded extremely cheaply, at 35 per upgrade early on.
