Bless needs to cost at least 3 AP if the source cost is removed.
I would take that deal.
EDIT: Quote from below
To be honest the fact that bless has a cost of 1 source point is not even the only problem. I recently downloaded a mod that made bless an innate ability constantly prepared but otherwise unchanged.
And after playing with it for a while I have to say that is it! You can use the point in dire situations and are not forced to plan ahead with bless at least the 1 point was the only cost so make it worth your investment! That should have been avaible from the beginning and made the blessing stuff much more usefull and finally worth the time and cost imho.
You mean if it still cost 1 AP and 1 Source point, but did not cost any Memory points?
Well, I certainly wouldn't mind if it cost 0 memory points to match the other god-given source powers, but if it still cost a source point, that wouldn't solve the balance problem between cursed and blessed surfaces, since enemies get a lot of ways to curse for free.
There just isn't really any effective counterplay to Curse.
