Hello,
Playing Discipline Priest, I track party Atonements with a Bar.

With 11.1 comes a new talent: Divine Procession which makes your Smite extend the duration of the shortest Atonement by 3 s.
The issue is that increasing the duration by 3 seconds resets the maximum duration of the Bar to the new duration.
For exemple:
I apply a 10s atonement: the bar starts at 10/10 (100%)
5 seconds later, the bar is at 5/10 (50%).
If I increase the duration by 3 s, the bar goes to 8/8 (100%) instead of 8/10 (80%).

WeakAuras2 has a fix for this: it allows us to specify a Maximum Progress value. for WeakAuras's progress bars.
This could be an easy workaround and a massive improvement as we could compare parallel bars because they would have the same scale.
