Okay, I've been away but I've managed to log on - here are a few humble suggestions (forgive me for re-iterating what's been said earlier).
Troligan to Hull 6, no doubts there (just read the written fluff). But it too could do with twin-linked minibeams, as could the veshetan (but both losing a few AD) the Tinashi is currently the trump card on battle-pl firepower - the Veshetan should be the faster, tougher alternative, and the Troligan the far slower, tougher alternative with the Tinashi filling the all-rounder role.
Torotha needs more manouverability (fluff, again - 2/45 is nowhere near close to 2/90), fusion cannons out at full range (18" and not the stunty 12" it has atm), and/or the same pulsar (antifighter, precise) as the Whitestar.
The Neroon could do with a few things in any combination - command +2 (the Centauri have that option in their beefier carrier, and at a lower PL by far)... adaptive armour is the obvious one. If they could jury-rig it onto that half EA built Victory, they can build it into their own top-of-the-line ships.
On top of that, it needs proper thresholds (and by proper, I mean 70% or above, like every other ship in the game - goes for the Liati too. I understand the reasoning given by Matt when asked, but IMO the 'too many new technologies' angle doesn't match the Morshin-welded-to-Sharkaan that we currently have). It could probably do with another 15-20 damage and crew, given the fact that it has the usual wafer thin hull.
The weapons or fighter loadouts on Shantavis, Neshetan, Sharkaan and Sharoos really need revising to make them remotely equal to the Sharlin. The tradeoffs atm in the War pl ships aren't remotely balanced.
Nials and Tishats to two per wing.
Stealth 5+ for every ship, or transpose 4+ to 5+ and 5+ to 6+ for every ship in the existing fleet roster.
The whitestar needs to be added to the Minbari fleet roster, or the ISA needs rules allowing for member fleets to take FAPs of ISA ships - the Minbari built the thing and were the sole operators for a few years... nuff said.
For new ships - the Liandra in at Skirmish would be nice (again, it was a Minbari ship according to LotR).
