This one slipped my attention when the latest revision of the Epic Tournament Rules came out:
Each player places six unique obstacle tokens, gathered from any X-Wing product, next to the play area, for a total of 12 obstacles. Then, the player with initiative chooses two of these obstacle tokens and places them into the play area at the same time, within range 1 of each other but not at Range 1–2 of either player edge. Then, the opposing player chooses two of the remaining obstacle tokens and places them into the play area at the same time, within Range 1 of each other but not at Range 1–2 of either player edge or any previously-placed obstacle token. The players continue to alternate in this way until all 12 tokens have been placed
So now, not only are debris fields legal, but so are the unique obstacle tokens that came with the Raider.
Cool!
