The old system also incites you more. Seeing 'At Risk' is more likely to make the average person do something about it, whereas seeing 'On Hold' is more likely to just increase frustration level.
And 'In Trial' seems like a term that should be reserved only for a new ad, even though that isn't the case.
On the face this change seems very bad.
"Previously strong, moderate, and at risk keywords will now be labeled as normal.
Only in trial keywords may be slowed.
On hold keywords will not show ads unless they move to in trial."
So the normal category is now very broad.
