Going through the rules for epic play a couple days ago, I noticed something saying that in lieu of using 3 obstacles in standard play, players could choose to use the CR-90 base template flipped over to the starfield side and that when ships went through/overlapped it they would follow the same standard obstacle rules from the original core set rule book.
Summarized Version: CR-90 template can be used as obstacle in standard play (possibly, competitive play).
