My new building idea is called the Altar. It’s purpose would be to target a specific hero for summoning of your choice.
Let’s say you really want Tarlak. You could set your Altar to summon Tarlak and for every 3 star hero I send to the altar it will progress summoning him by say 0.5%, for every 4 star hero 3% and a 5 star hero would give something like 5%. Once I reach 100% it summons Tarlak to my roster and all the other hero’s would be lost.
The numbers could always be tweaked to however SG see’s fit but I think this would be a solid solution for 1. long time players who have a big roster but are still searching for very specific hero’s they still need and 2. When you spend big for a hero and fail to pull them, this gives you a back up plan for all the duplicate / unneeded hero’s to still turn them into something valuable.
SG still makes money because you need an ample amount of hero’s to sacrifice at the alter but the player is happy because in the end they get the hero they wanted.
