Because dungeons were designed with these story paths in mind, these paths are completely different from the explorable paths and thus do not apply for raids. So I'm acknowledging my unfamiliarity with raid content in GW2 here, but if I understand your post correctly, there is no 'story' to the raid content?Dungeons have a big part of their story in the story mode, which is strongly interwoven with the personal story. Their explorable modes also contain bits of story, which takes place after the story mode story. However, as Grogba already said, explos are totally different from story mode. They have more or less similar locations, but that's it. A possible raid infantile mode is a totally different story, since that one would be a poor copy of the normal mode. Dungeon paths are no copies.
