why is castrum and praetorium not an instance

[bswpayton]

Do you realize how few people would be running it if it offered no tomes? Are you really asking to dedicate hours of queue time for a few cut scenes?

edit: And it being a solo instance would make absolutely 0 sense if you actually care about the story.

There would be no reason for people to run it if it was a solo instance , it would just be a solo thing which would be better so more people could see the story instead of going out of their way to see something they are entitled to see anyway
