While I instictively dislike a call to ban something because it's broken (it's an easy, lazy response- fixing things is harder, but more worthwhile in the long run) I agree it is open to abuse and a not particularly honorable tactic (speaking as an ISA player with 12 Bluestars, 10 Whitestars, a carrier (+10 Fighters) and 2 Victories; I still don't think much of it even though it could work out great for me-25 JPBs in one turn!) I would suggest simply making it an "opponents consent" before the game house rule in the short turn, and apply the 3D rule in the long run "Difficult", "Dangerous", "Desperate"; keep it but make it difficult to pull off, with a non negligable chance of "hurt me plenty" if it fails, so that it is largely a desperation tactic. It sounds as if that is what is being done, so hopefully...
I also would make the AD (semi) dependant on ship size; yes you're still ripping a hole in space, but a smaller hole requires less ripping, or halve the dice for AJP, since they theoretically control the rip better, so cause less "waste energy"
On a side note regarding dodge; I would assume you aren't really dodging the energy wave front, more using your agility to ride it like a surfer (like sailing ships turning and running before a storm)
Regardless of what happens with the process I do think vorlons should have the same opportunity to (mis)use it as any other fleet, so would need a scout
