All story is optional. But you're asking for them to take time creating Content for your cult. (Yes, you Revan Fanboys ARE a cult!) When BioWare could, instead, be working on a continued storyline which more of the community would enjoy.
maybe for those who chose to follow the Revinites there should be a longer story line but for those who dont like Revan they dont have to do the story line. Also involve more rewards such as armour or cosmetics or titles for those who do chose to follow the revanites. Also maybe involve a story line destroying the revanites so you can choose which if you dont like the revanites.
