Yes, but even leveling your way, you are now 70 and therefore not available to group with Crissa if you want a group that's going to be equally challenging and rewarding for both of you. I'd also guess that even when leveling slowly, you probably only did each midlevel dungeon a couple times or so, while you've done many, many more Lab or Gazluk Keep runs.
As I said, I don't really have any good solutions. I just think that players who aren't max-level yet are going to have some additional problems getting groups.
