Just to throw in my 2 cents, Laufey is correct. no ship could withstand a dozen torpedos impacting shields at once. (at least, none of Cardassian design). Secondly, the purpose of a sensor dampening nebula was to prevent sensors from locating ships. Means no weapon lock. How did they stand to fire at a Cardassian ship in such a condition? that many, from 3 ships, on manual? She's gotta have 3 Worf level tactical officers to even have a chance of pulling that off. Finally, how many move and fires does she get per post, per turn, before its too much? Cloak, decloak, fire, cloak, decloak, fire = 1 post? 

Just wanted to point that out.
