Don’t over-cap shroud or reaver

About the only place it could even be considered to have a rotation is its burst windows, but even then you have a lot of flexibility and mostly just guidelines to follow.
And there is a set order with those priorities to line up your utilities and shrouds. Having a priority setup doesn't change the fact that reaper does have a rotation with a set opener and timings to continue to line up those openers for every burst window. If you drift off that rotation then you lose your burst windows with the other raid buffs.
