My guess is those bigger numbers are there to compensate for the out of momentum DPA.
The set feels completely different when momentum is up, though I'm not sure 80% is the real uptime in actual play. Doesn't feel that high.
Seems a hard mechanic to design around.
The dots i have no idea tbh, dots tend to be better on paper though, since people don't usually let them tick out. See the complaints about Savage underperforming.
