Developers : Healer design mentality needs to change

[Saefinn]

Or they could have changed the Balance from a straight damage potency buff to something else, since that was the main problem.

Possible, but I suspect the problem that'd then follow is a different buff gets fished, like The Arrow. If the pay off for fishing is greater than using the card you've got then fishing will happen because there are people who will try to optimise their best numbers.
