For those who are either grinding for The Mountain Top now or planning to, take this tip into consideration. The most difficult part of the quest will hands down getting the double kills with gernade launchers (yes, it has to be with specifically gernade launchers). Similar to the Luna's Howl quest, you'll want to get all your kills done before going for fabled, or else it'll be 10 times worse. So what's the best way of knocking out those double kills? Having the enemy let you get them. In other words, you'll need to get a 4 stack together and match up with another 4 stack and message them saying you want to farm these kill. Send them something like: "GL doubles?". And if some team sends you this, you should comply with them. All get together in a party and discuss it out. Take turns getting double kills with gernade launchers, and his will be SO much easier than doing it legit. You can also talk out more precise terms, say if the enemy team really wants the win in exchange for letting you kill them a bunch for quest progress. Or maybe they want hand cannon kills for Luna's Howl. Whatever it is, you can help each other out and make things so much easier for everyone. I employ you to try this, as this'll be so much easier on you doing it this way. A lot of players who have gotten this gun or are currently grinding it out would agree that the double kills are the most frustrating and time consuming part about it. But hey, maybe Bungie could actually make this part of the quest reasonable to do and change it, but let's be real they probably wont. Try this out! Let's make this a thing! Share this around so people know what's up! FYI: I'd suggest doing this at low ranks , so that players likely won't be so inclined to win that they'll not trust you and ignore your message.
