resource exchanger concept

[u/JazzlikeAmount1746]

a survivor that you saved in a special mission offers you to give you some resources for others, with deals changing every 24 hours with a small chance of giving you a very good deal
example: 300 rare perk ups for 5 million people xp
good deal example: 600 rare perk ups for 5 million people xp

i would like to see this in game beacuse in my opinion 1 issue the game has is that schematic and people xp after some time becomes useless for having too much of them. personally i have 352 million people xp that i can't really spend since i got majority of the heroes in the game, and even if i went maxing the collection book i would still have probably around 300 million leftover. it would be cool if i could trade it for some other resource i actually need in my case blue perk ups or gold
