No-one is asking for two of everything. No-one is saying Vanilla users should have the shield brothers, however, they should be able to do a tuned Sepkis Prime if it becomes the Nightfall, they should be able to participate in all the Crucible stuff they could before using year 1 gear and maps (COD allows people with and without map packs to still play pvp. Its not like the ability isn't there, we already have tuned strikes based upon light level etc and Crucible doesn't even count levels.
