Considering allowing post-roll Karma use, rather than pre-roll and spend 10
Right, so mechanically
Need to get a 50, spend Karma
Old way – Expected Value of Karma Spend = 17.8
New way – Expected Value of Karma Spend = 12.25
So an average of 5.55 Karma better off in that situation.
Sounds pretty reasonable, to me.
Or use Karma half a dozen times a session in that case, 30 better off in the long run, give or take.
This was based on considering DC Heroes genre rules..which varied what you could do with Hero Points and how many you could spend.
The above would be for your classic four colour situation.
