There is strikes for the Vangaurd, and they're great, but what if there was another kind of survival-type strike? Something like a fireteam of 1-3 players vs wave after wave of Thrall (because they don't have guns). They could come in larger numbers and gain a level (up to 30) with every completed wave. I was thinking it could be like The Summoning Pits but that's already a strike, so I don't know if that would really work. Thanks for reading, let me know what you think!
