There is insufficient value to attract purchase.
There is many offers that does not make sense e.g. 1pack for $X, 1 skin for $Y, etc
But as seen most players dont mind the current setup, thus the Dev wont care.
The current setup still works as a whole.
The battlepass is interesting but too restrictive in term of value. Player would want more more flexibility to get the rewards they want rather than a fixed/random reward pathway.
