There should be another strike playlist implemented into the game that involves different damage bonuses. Ex. Arc, Solar, Void. Just like it is in the nightfall. The level should be set to 28 and the enemy rating should be epic difficulty. If you wanted to spice it even further, you could make it so players had a limited number of lives per game. If all players ran out of said lives, the mission would end just like the nightfall. To compensate the increase in difficulty, there should be an increase chance of engrams and possible legendaries for completion with no one on the fireteam being downed. Or you could make it so the faster you ran the strike the better the rewards. Just rambling here, but I would love to actually take advantage of all my damage types in the normal strike playlist.
