A. Equip aftershocks on striker B. Wait till enemy goes full retard, trying to capture one zone with 6 people. C. Just before they capture it, throw lightning grenade into cluster as they capture the point. D. Wait for person to respawn and walk into your lightning grenade. E. Can be done with aftershocks on fist of havoc too, same idea.

I haven't actually achieved it because i'm never lucky enough to have all 6 of a team standing in one spot long enough. However, it is theoretically possible. I.e. 6 mens go to grab B flag, one of which being a sunsinger with his super. You run aftershocks to increase the duration of lightning nade to 6 pulses. Throw said ubernade on B-flag, get 6 piece, lock rezzes and tries to think he's supersaiyan and then dies again to ubernade. 7th column achieved, 1 nade.
