(My recent fold space experience is with an Earth controller that drops Volcanic Gasses/Earthquake/Quicksand and then Folds Space enemies onto the patches.)
Nothing that Fold Space does slows or stops enemies.
You will want to Mez or Debuff a group before bringing them in close, and if you miss any enemies before you fold space, they will arrive ready to attack you.
Another quirk of the power is that for reasons I do not yet understand, it sometimes teleports your victims into a neat line extending away from you, and potentially outside the range of your Auras and Patches.
If you replace "then get into them" with "Fold Space" then your process should work fine. Just be mindful that depending on the distance traveled and your move speed "get into them" might be faster than the Fold Space Cast time + Animation. Oh, and Fold Space can miss, so some enemies might not get dumped into your Auras and Patches, and instead just shoot you from a safe distance.

Ack! I just saw that this post is a year old. I wonder how it worked out?
