Fates and Leves are "Optional" & level synced, My ideas suggests coaxed or unavoidable interactions. I gave them props for the Treasure hunts. Option 3 is regarding the instancing. IF they plan to rely on it heavily why not make it more flexible? Also Odin & Behemoth are fights for the top DPS Parties to get placement which is no different than competing for mobs tagging. If your party is the weaker of many you get bronze vs stronger teams, so world bosses are slightly competitive.
