Honestly it is fine to merge them all
But we get no compensation for double increases unless you spend money
They claim to want to reduce the gap between f2p and p2w, but then do things like this where it literally halves the number of heroes we can increase every month.
The double drop events DO NOT help if you don’t have stamina to spend.
Merges reduce the number of players who can get rank rewards in contests, invasion, Arena and Coliseum. This demotivates players and they leave the game.
So many people have raise this and some even given great suggestions and ideas on how this can be overcome - but from me as a player there is no evidence that anyone hears our cries for help.
It is just sad that it will inevitably end, sooner than we hoped.
