Expand the Praetorian arc level ranges

So, I've been playing through the Praetorian arcs recently and I've been finding that Praetoria just ends WAY too soon.  I suppose it's fine that you get tapped to leave Praetoria at level 20, but the amount of stuff that you can do IN Praetoria could easily be extended another 5 levels.  The arcs are so experience dense, that it's easy to miss out on content even if you stick with just one chosen path.

I don't know if this is something that's actually possible, but it still bothers me when I have to turn off my experience gain just to do an arc I enjoy because if I don't, I'll be leveled out of it and miss out on that story.
