I know i'm a bit late to the party, but I found what I think is the easiest and fastest method (~10 minutes give or take).
Head to Verina Mart in Ravatogh. It is an outpost in the Cleigne Region, located at the bottom left of the map in Lucis and off by itself in what looks like a lasso when looking at the map.
Accept the "Verinas Mart Under Threat" from the man at the Food Stand, and head to the location where the hunt is. Simply walk up by the Wyverns and warp-strike one from a distance, where more often than not, you'll knock them over and give you a chance to start the chain by warp-striking again.
If the warp-strike doesn't work the first time, just run outside the red ring to end the battle and immediately warp strike again. Because there is only 6 enemies at this hunt, you'll have to head back and start up the Hunt again when you're done, but it's minor for how fast this method is.
