The cheese is back (Destiny)
I'm impressed as to people's ability to cheese what seems uncheesable. It's not as cheesey as pushing Atheon off, but it's definitely unexpected.
Spoiler:
If you have someone die right before Crota's shield goes down, Crota will summon the oversoul and stay in that pose allowing the sword bearer to get in tons and tons of hits. It only takes two rounds this way :-p
