I guess its more liekly to be a couple of the Narn raid ships with SL emines - (K'tans?), a Var'nic or two. Who would take a G'Quan - seriously!/
even a more balanced 5 pt raid centauri fleet could look like this
Balvarin (+1 Command and its just a great ship)
Elutarian
Demos, Demos
Demos, Demos
Maximus, Demos
Against Narn (or anyone save poss Minbari/Shadows) a Horrific Alpha Strike ability, defensive ability, fighters and base Iniative of 4 means you are quite likely to get first shot in. All ships all stop, First turn kill a ship, second turn repeat..............
It would also work against fast fleets because on turn 2 they can split up as needed.........
