Imagine a nightfall strike, aside from the normal nightfall, where the burn changes constantly throughout the mission. Let's use Omnigul as an example. The first part where you clear out the Fallen could be arc damage, but as soon as the hive spawn, an alert sounds and the burn changes to void. Or it could start out with solar and change to arc, etc. A notification would always alert you whenever the burn changes. Another way to make it interesting, would be to randomly switch the enemy's shields as well. Sometimes they might match with the active burn, sometimes they might not. A nightfall like this would be much more difficult, of course. So I feel that the rewards should be greater(No energy or shards for example). Would this be an interesting change to Destiny and would it be more challenging?
