Why healing is conjuration?

[Melcar]

There's nothing ambiguous or confusing about what having Fast healing 5 means unless you lack familiarity with very basic game concepts and research skills.

Ok... So for me its simply that raw positive energy should not just give an ex abilty but simply heal. When it gives the already very specifically defined ex ability fast healing, its healing undead as well! I don't like the fast that positive energy apparently can give the fast healing ex ability. IMO it should be continues healing! Why does it matter you say, because fast healing is a specific defined thing.

So for me there is inconsistencies. The problem is that the traits of raw positive energy has not been defined, therefore it can do everything. I dont like that!

If both living and undead ar caught in ANY positive energy of any form, the living should be affected by some healing and the undead som harming effect. Thats not actually what happens!
