Rewards for storymode?


Was disappointed that after slogging through the story mode, all the way to the end that there was not a special reward or hero for completing.
Makes it feel like there is no point. Don’t know how keen I’m going to be to play season 2 of the storyline.
I know a lot of other players feel the same…
Could there please be a special hero/chest/reward for completing as an incentive?
