If the goal is a sacrifice play to save your team, knowing that you're all dead if you don't, yes.
This is why you take that 5 edge action
....or burn an edge for smackdown
Or both.
Besides adding both 12 meter to the AoE and 6 to the damage will probably get you killed anyway ;-)
...and a 8 meter radius if you also amp the area 6...
6 amp on area will increase radius from 2 meters to 14 meters (or a total of 28 meters across) - which is pretty huge.
