Started grinding for Grasp Of Malok today. On our third Run it dropped for me. Kept grinding for it to see if it would drop for the fire team members, it dropped for me again three runs later. It literally took me longer to find a fire team to farm with than it did for it to drop. Both Rolls were very similar, so I kept farming. I invited a friend of mine and we ran thru Omnigul around fifteen times when it dropped again, but for my friend. It had way better perks than mine. Within a little more than an hour I seen it fall three times. Hopscotch Pilgrim was more elusive than this Pulse rifle. I will keep farming until I get a Drop with the Roll I am looking for, or pretty close to it.
