Legends will have the smallest role, if they actually follow the weird mechanics of the Crisis, the Waverider would be completely unnecessary because of the Warp Zone. The Monitor doesn’t find them strong enough so he sat disapprovingly, he needs them strong because they consist of half the heroes.

Arrow will be completely ruled by the Crisis next year so Arrow will be most important, it will also introduce the absolutely vital Green Lantern lore and Harbinger into it.
