All 5 in a group should be faster, given the grouping XP bonus.

Of course, if the PLer is doing all the work, then maybe alone would be faster, but then you'd have to do it 5 times, so I'd still go with all 5 at once

Unfortunately, the druid is only 60. There are some spells and AAs at higher levels that make them very effective PLers. My main in the mid 80s could PL very effectively.

With a PLer that low, I would almost guess that the 5 in a group could XP just as fast, if not faster, and just skip the PLing.
