Very simple suggestion which is pretty self explanatory. Increase the amount of daily point refills to 3, this increases the demand for points and creates a sink to remove them from circulation.
This will increase demand on a heavily saturated market without injecting more cash into the system like the pawnshop used to. This will not only impact stat gains but also the available energy for chains and wars.
optionally you could also scale the cost as 25,50,75 points for the purpose of balancing further increasing the demand for points and taking more out of the system as a result.
