Landis181, you won't be able to participate in Incursions until you're level 30. Just keep running the story missions on hard if possible. If you can't get a group through matchmaking, then play on normal and solo them. Make sure to run the side missions in each area before moving on. If you keep to this, each time you move to a new area, you'll either be right on par level-wise or a level or 2 above, which will make it easier for you in the long run. Plus, at 30, you'll want to have all side missions completed anyway. I have a couple lowbies that I can run with you. Hit me up on the facebook page I posted in your other thread.
||| ZIG |||, we have a couple dedicated groups running DN - both just 4 Horsemen and the whole instance. Check out
The Elite 2nd Wave and post your GT and what you're looking to do.
