I guess the current reason why we don’t have different war rewards and ascendable 5* characters is the same as it has been. Staffing issues and the additional time needed to create 6* characters, because you need to create a 5* and a 6* character.
There is a very very very simple solution to this problem. I am certain there are a plethora of characters in incredibly limited circulation throughout the game. Think the 1 time war reward red Andrea, for example. Why not make an ascendable version of these incredibly rare characters, pt them in the promo, then use the left over time to work on legacy toons, war rewards, etc?
Scopely would still get paid, because their rarity would in essence make it a new toon to the vast majority of players, the players would get the war rewards and legacy toons we want, AND it would greatly increase the legacy toons list. Seems like a win, win, win, to the point that I’m amazed it isn’t happening already.
