I've done it legit twice but I cheesed crota on my low level alt for my third run. It felt wrong and I didn't feel like the reward came with a fanfare or joyous whooping from the rest of the team. Just loot call outs and swift disconnections from xbox party. I won't be cheesing him again anytime soon, even on low level alts. I want to beat him correctly and bathe in the beautiful feeling of success for a battle hard won. I really hope bungie patch this problem so the necrochasm is well earned. Not cheesed by a bunch of Christmas noobs.
