It would be the same monetary outcome...but if you consider the benefit of the players not feeling robbed or disgusted by the high amount of money for packages right now, don't you think, these players will stay longer and spend more?
Imagine a whale buying 1 package for 50 dollar....and 10 low spender not buying it
now the prices are only half of it
the whale would probably buy 2 packages of 25 dollar now....how many of the low spenders would buy one now? Even 1 would increase their profits (and they do not have any costs at generating blue shards or whatever)
It sounds logical but i imagine an insane amount of analytics is going on in order to maximize revenue and they know what they are doing.
The model seems to be based on getting a constant heavy stream of players in, who can be monetised before quitting. I would guess 90% of cost is on marketing and art- and i am sure the game (which is very much like a casino) is carefully tuned to encourage people to spend for another dopamine hit.
I dont know for sure, but i imagine player actions are logged as well, in order to offer the most tempting packs, i have been six starring a champ today and have had packs with 5 star chickens offered for example.
