Heeeeeey if you guys play as a Voidwalker with the infamous Obsidian Mind super setup (there are tutorials for how to make it all over the internet), I suggest you try doing this in the Vault of Glass just for funzies! Once you get to the Templar's well (you can stay up on top the whole time), put the perk "Lance" on for your void bomb. Get a rocket launcher with cluster bomb (hunger of crota works well), and Icebreaker and some scout rifle, preferably with Explosive Rounds. Now, when the legions spawn, you can recharge your super almost immediately and get easily over 150 kills before the Oracles appear with the weapon combination I stated above. The nice part - it's surprisingly effective and can make it easy for one person to hold down the middle all on their own. If you're ever bored, take my word for it and try this. Loads of fun :D
