I would like elemental primaries to return myself. I don't think beating the raid should be involved though. Give good weapons that already have burns from the raid drops but allow for infusion on every legendary weapon for the element of your choice. It will keep all weapons viable but give us the opportunity to customize our gaurdians even more. Elementals are good only against the proper shield anyway so whats the big deal? Fatebringer was used so much because its skills, not its arc burn.
