if you got mounts on all yours guys there is a way to skip all the annoying mobs and go straight to zombies. i would suggest just grinding those and maybe back track to scarabs then reset. I did ZF to 53 grinding just zombies and the event near the end of my levels. Could of even stayed until 54, but I went to BRD to start on some gear.
your team comps would help to suggest level brackets of dungeons.
