Sync Backlog priority changes in the epics and initiatives view

Hi,

I'm not sure how this is supposed to work, it causes a lot of confusion here. We have about 20 Projects, which we enter as Initiatives. For these we enter epics and stories. All this is happening in the "Initiatives" view. We never even open the "Epics" view, because it's just a chaotic collection of epics without context.
Now we prioritize by dragging up and down the initiatives and the release streams.
What happens is: priority is not adjusted as we want, because the priority in the epics view (which we don't use) is overruling it.
From my perspective the priorities between initiatives (on the initiatives view) have no effect at all. Whats the concept behind this?

Thanks, Juri
