I disagree with the original post. Honestly, I thought the Narn fleet is significantly improved with a couple of exceptions. Here is my opinion of the current fleet roster.
The Good:
G'Vrahn - I can't say enough about how good a ship this is. Teamed with the Var'Nic and Thentus it is spectacular.
T'Loth - FA on the plasmas is a huge improvement and the changes to beam rules make it harder to beat through its vast reserve of hp. It is a durable initiative sink. It isn't the heaviest-hitting raid level ship but it will be in the fight to the end and FA arc with decent range means you can't ignore it either.
Thentus - Good ship as always. No significant changes. The Thentus always was a good ship but the old Ka'Tan was so overpowered that no one used it.
Ka'Toc - Same as above. The de-powering of the Ka'Tan returned the Ka'Toc to its rightful place in the sun.
T'Rakk - My god this thing has a lot of hp at skirmish. It is half of a T'Loth, literally. It is pretty quick for a Narn and actually can turn too. I am not sure how skirmish ships kill one of these. Ranged firepower seems kinda weak though but you can't have everything.
Var'Nic - This ship really rocks at raid level. It is quick AND agile AND has good firepower and good range. Keep fighters away from it though.
Dak'Kar - Happy times again. If only the thing had more launchers but with fewer dice per launcher to add flexibility. A couple of these in your fleet will destroy light ships quickly and hurt medium ships. They have decent hit points but low hull and are slow as molasses. Beams are no longer the bane of their existance
The Bad (Or not much improved)
G'Quan - Marginal improvement if at all. I would've increased the beam dice by 1-2d, especially since the secondaries are so short ranged and it is boresight. 1 launcher hurts a lot too. I would also have preferred 2x3d launchers. At least that adds flexibility. 6d of one-shot e-mine is not nearly enough. It needs more laser, decent secondaries (more range) or more e-mine. (Possibly 2x 6d launchers with a special rule that it can't fire both in the same turn.)
G'Quonth - Just get rid of this thing already. It doesn't need to exist. War level is crowded with good stuff for the Narn and I can't say I'd ever use one of these over a G'Vrahn or a Bin'Tak. They have a lot of firepower but have the bad combo of fragile AND slow at War level which will be their downfall every time. Enemies who shy away from pouring damage immediately into a Bin'Tak will rejoyce and unload on this thing.
G'Karith - I agree with Celisasu. I thought it was better with 4AD bow and aft. This gave it better fighter clearance. Truthfully I would have added 2d of side pulsar mines too. 8AD front is not nearly as useful. It isn't that hard for faster fighters to stay out of the cone.
Gorith - What is the point of this thing other than to show the evolution of the Narn fighter programme? It's no Kotha but it sure isn't any good either. It can't dogfight well, it is no faster than a frazi and it is a poor anti-shipping fighter. It is only slightly better than the Frazi at the stuff the frazi is supposed to be lousy at and it has NO real good points. If they were at least cheaper than Frazis that would be something but they cost the same too.
The Ugly
Ka'Tan - Not sure how 1x2d e-mine is supposed to be useful. They should've mounted a small pulsar mine (3d) on this thing instead. That would have made it a decent fighter-clearance unit. It is listed as an escort (without the trait) but I am not sure how it actually supposed to escort anything. Multiple Ka'Tans are useful against really BIG fighter formations (Gaim and EA mainly) though because they can create a large firestorm by launching all mines at once.
Rothan/Rongoth - I never liked these ships. At least they are cheaper now but they are still not good in my opinion. They have decent firepower for skirmish but a Ka'Toc or a Thentus will almost always be a better choice. At least they aren't boresighted.
Wishes for 2e additions/fixes to the Narn:
Please for the love of all that is holy improve the G'Quan. You see the ship using its lasers in the show, not it's e-mines. I would like to see potent lasers, even if it means a reduction in E-mine damage.
Please do something with the Gorith. Boost its speed at least to 12 or make it cheaper to buy as independent wings. At least that gives some reason to use it. Also, when is the Narn Tarza torpedo fighter going to make an appearance? At at least it would give more options other than Frazi, Frazi and more Frazi. EA got all the old starfury variants back, how about the Narn getting the Tarza back.
