GoDisease is only really beneficial with 2/2 Epidemic. The rotations to make it work without will cause you to lose the extra Heart Strikes, which are the entire purpose of using the glyph as blood. The math done about using GoDisease assumed taking 1 point from Morbidity to get 2/2 Epidemic.
Okay, that's the information I was needing. I was driving myself nuts thinking that I was doing something wrong because my diseases just didn't last long enough. I'll respec and try out the rotation you listed and see how it goes. Thanks a bunch.
