Neshatan vs Sharlin = Same guns, 1 pt difference in hull and stealth. Neshatan has a minor amount fewer damage/crew. Same maneuverability, so essentially the same ship.
Troligan vs Tinashi = Troligan has same stealth, 2 less beam weapons, 1.5 : 1 damagee and crew, 1 less turn, 3" less movement. Offensive power takes a hit, but is a much more durable ship, it's a tactical choice. (I still think the volume of ships I had would have countered even the higher movement of the Tinashi, especially since most of mine had 2 turns also.)
Tigara vs Teshlan = Same maneuverability, Teshlan has 2 more inches movement. Tigara has overall more firepower, but at shorter range, otherwise they are identical.
Laranos,
Good points, but let me see if I can explain my thought process.
Sharlin vs Neshatan
Maneuver - Same speed, but Sharlin has 1 extra turn, which gives it the same turning radius as many other races' Raid level ships.
Offense - Same Beam, but Sharlin has 20% more Fusion AD.
Defense - On a shot-for-shot basis, the odds of doing a point of damage to the Sharlin or Neshatan are virtually identical. This holds up inside 10", outside 10", and with basic, AP, and Super AP weapons.
Damage - The Sharlin has 7% more damage and 6% more crew
On all counts except defense (in which it ties), the Sharlin has better stats.
Troligan vs Tinashi
Maneuver - Tinashi has increased Speed and 1 more turn.
Offense - Tinashi has 100% more beams, but at 5" lower range. Troligan has 8% more Fusion AD.
Defense - The ships have identical Hull and Stealth
Damage - The Troligan has 45% more Dam and 52% more Crew
As you said, a tactical choice of Firepower vs Resilience. Consider this for a moment however, by the numbers, a Tinashi on CF! will do 7.5 hits against a Hyperion, with a third of those being Crits. Again assuming an average Dam/Crew of 2 per Crit (I ran the numbers the other day), that's around 18 points of Damage and Crew. With only average rolling, the Tinashi has just crippled (or likely destroyed) 1/15th of your fleet before it could do anything. By contrast, the Troligan could only do 3.7 hits, yielding roughly half the damage and allowing your Hyperion to survive long enough to likely bring it's own guns to bear. Replacing both Troligans and a Morshin (which couldn't do any damage at this range) with Tinashi, average rolling will allow you to destroy 1/5th of the EA fleet before those ships even have a chance to fire.
Tigara vs Teshlan
Maneuver - Teshlan has 2" more speed.
Offense - Teshlan has 2 Beam to the Tigara's 0. They have equal Fusion AD. Tigara has Molecular Disruptors and an Anti-Matter converter. Overall Tigara has more AD, but Teshlan has better stand-off firepower.
Defense - The ships are identical. It must be noted however that the Teshlan's greater stand-off range means that it will benefit from the +1 to its Stealth for more turns and is therefore more survivable.
Damage - Identical.
Again, a choice of tactics here. Do the Minbari use weapons which force them to lose Stealth's distance advantage, force them to enter the EA's secondary weapon engagement range, and allow EA to use their own defensive systems (Interceptors), or do the Minbari pound EA from outside EA's range, with weapons that the EA can't intercept, and gaining +1 Stealth?
Fighters (totals)
Troligan - 2 Tinashi - 0
Neshatan - 0 Sharlin - 8
Morshin - 16 Morshin - 8
Tigara - 3 Teshlan - 3
Total - 21 Total - 19
Turn 1 Deploy - 17 Turn 1 Deploy - 13
Admittedly, we're short a few fighters. If I remember correctly, your EA fleet could only field 14 by the end of turn 1, so we're not sacrificing much in the way of defensive capability.
Sooo.....lets look at Turn 1.
Lets assume that we're starting 36" apart, nobody's in Hyperspace, and EA has decided to close the distance since trying to win a ranged battle against Minbari isn't a good idea. Considering Minbari Initiative, EA has been forced to set up its fleet first and since I know I'm outnumbered, I'll go ahead and squadron the Teshlan.
Given our movement and yours, every Minbari ship except the Morshin should be in range. Because we got to set up after you, we also were able to position our fleet to ensure that we're faced off against the ships we want to kill this turn.
I decide to ignore everything except the Hyperions. The Tinashi, Sharlin, and the squadron of Teshlan each go on CF! and take a different Hyperion. Given the numbers above, I've either crippled or destroyed 2/5ths of your fleet. Is it possible that you've taken out one of my ships before it could fire? Sure, anything's possible, but only 1/3rd or less (depending on your targeting selection and luck) of your ships have a chance of hitting. Given that the only ships in range at that point would be the Olympus (missiles) and the Omegas (Heavy Lasers), the only ships you could probably destroy outright would be the Teshlan.
Against the original Minbari fleet, the only ships in range in Turn 1 would be the Neshatan and the Troligan, which only have about half the long-range AD as the above fleet.
