I would prefer a upgrade to the Year 1 raids. Specifically that drop Year 2 variants of the gear. However, I would be satisfied with a way to bring the Year 1s to Year 2 through an upgrade, that made them into a year 2 variant. Especially with the Vex and Necro. Bungie, you put in the time to fix them after you broke them, the Vex specifically, and then made the useless.
