When checking hero details of my raid matches, the health presented in preview details is lower than in the actual battle.
I’ve noticed this because I only raid within a certain health range compared to my heros and with a trophy lose count -19 and under. It seems to be most benifitial.
However, if the preview values don’t match the actual hero values, then I don’t have many chances to win. I would have not attacked those enemies bases on their actual health values.
