It was a tactic that served Wales well in completing a Six Nations Grand Slam this year.
But Warren Gatland's team never went to the extremes Exeter Chiefs did on the weekend to stretch the controversial use of a ruck loophole to the very limit.
And in the wake of their 24-20 Gallagher Premiership victory over Worcester Warriors, the west country giants have come in for some heavy criticism online with fans calling for the tactic to be banned.
The 'ladder rucking' ploy sees players attaching to a ruck to form a single line of consecutive players in a conga formation.
The technique means the hind most of foot of the ruck is several metres away from the nearest opposition player, and gives the scrum-half space and time to avoid any potential charge-down of a box kick or tackle.
An image of the loophole was posted by Chris Clarkson on Twitter. He wrote: “The sooner this ludicrous loophole gets taken out of the game the better. Looks ridiculous.”
The Tweet drew hundreds of responses, most arguing for the loophole to be closed as soon as possible.
Wales and Harlequins hooker Scott Baldwin, did, however, point out that Exeter and England prop Harry Williams hadn’t bound onto the tackled player and that it was no longer technically a ruck and that the ball was in fact out.
Wales employed a shortened version of the ploy in the last few seasons and it remains to see if the updated Exeter Chiefs version catches on or whether World Rugby's lawmakers plug the loophole.
Here's a sample of the reaction
