I don't usually run with catapult, as I prefer Increased Control. That being said, I'm sure that I could enable catapult, put on full agility gear, and run like mad. However, this changes my play style. I don't think it's unreasonable for a group to run "as a group" to get to a common goal. If someone is behind me, I usually go back and check on them to make sure that they aren't stuck by mobs and such. Even with the strike grind, the overall 2-3 minutes that this might take really don't amount to much in the long run and (IMO), makes things easier.
