I suggest that there should be an option to adapt the faith of the reroll fodder.
So it goes like this, for example,
I want to reroll my 5* to Ares
I use a 5* fodder with Ares faith to reroll
I am given the option to copy the Ares faith (250k fee) or go for random (100k fee)
Reason: There's too much rant thread about faith rerolling. It is very painful already to sacrifice a 5* unit just to reroll another 5*. This would lessen that pain at the very least. I also wanted to say that, with all due respect, the pixie reroll system with it being cash or time limited, didn't fix this reroll system problem at all.
