Siva is one of if not THE community favourite creation and aesthetic in the destiny. Your refusal to bring it back when so many people want it, just baffling. Just adding some siva Ornaments for exotics isnt enough. It has almost unlimited potential to create cool origin traits, armour bonuses and weapon perks. ... I'll give you this for free. Siva + vex is the way to go. You literally teased that in year 1 of destiny 2. Just have Maya reactivate siva. Siva takes over a vex mind with a leftover Rasputin order. Then you have a new faction of enemies to use within the story.
