I wished Mystery Heroes was like that mode from Junkenstein’s Revenge “Mystery Swap”. A challenge mode.
Instead of each hero being swapped to a different hero. Both the teams will be swapped to same hero wherever they are. So say for every 1-2 mins everyone would be swapped to Rein. Ult charge will be even faster and if they die the ult would go back to zero and the same goes when the swap happens.
A UI should be shown how long until next swap happens but it won’t show which hero would the next.
Mystery heroes was fun before new heroes were added. It’s boring to play now when the team get more than 2-3 tanks or when RNG favors one of the team. With OW2 the tanks would be even stronger.
