Ok, let's say lover status would require 1000 disposition. 1000/[130-150] = [6.5-7.5] per day, without any additional events, only via normal GMs. It's a very low number compared to the current system, when even a simple chat gives randint(1,4).
I'm not against it, but it means that either disposition should be noninteger and for example chat will give from 0.2 to 0.5, or max disposition should be more than 1000. Because otherwise there is no way to make simple options like chat balanced.
