The only thing you need to justify that Bungie doesn't stick to lore in game is the freaking Taken Archon Priest. Now THAT makes no sense... literally, you will have to make a new timeline to make that fit in. No less to explain it. -- Of course, you know what they're really going to do, right? They're not going to 'remake' The Nexus or Taniks physically, just the strike itself. They're going to do to them what they did to Valus Ta'aruc and the Taken. They just put in a bunch of Splicers 'trying' to get there before you. Which makes not sense... but they won't touch the bosses. At least, I hope not.
