That is the most ridiculous thing i have ever heard. Very few other scenarios are enemies close enough like that for you to kill 10 plus like that with your nova bomb. Its mostly hive missions. And not many. I have seen this strategy many times in person because i know people who have had the helm before xur sold it and it does NOT work as good as shown. But if you wna make it a huge thing about how good it is, when it really isnt, and get it nerfed to be even worse than it is, be my guest lol.
