Triggy,
Your evaluation of the Xorr is intriguing; unfortunately, I cannot agree with it. We have, separately, classified this as a mistake ship within my local group. You took a Xorr? You made a mistake...
We find it an explosion in a jar, rarely able to get close enough where its SM capability makes any difference at all. For example, consider the expected yield on it from 1 CAFed Omelos (which will happen, usually, at least to half the Xorrs when opposed by an equivalent number of Omelos).
14 dice of pulsars: 75% hit -> 10.5 hits -> 10.5/10.5 damage + 1.75 crits (typical crit is 1.1/2.0) -> 14.35/17 and Disruption Torpedoes can easily generate the remaining 3.85/3.
Even straight dice find this ship on the losing end:
14 puslars -- > 7 hits (other math same as before, just apply 7/10.5 factor): 9.57/11.33. D-torps: 2.67 hits --> 4.90/4.45 + 0.45 crits --> 5.89/6.25. Net: 15.46/17.58 is crippled and skeletoned by large amounts. How useful is SM going to be now?
Add to this the fact that a Torotha can hit it with an AJP bomb and virtually guarantee that it is crippled without so much as rolling a die! Insane for what is supposed to be an iconic ship, much less one considered good.
And how badly would you need SM anyways, the thing has two 90's and nothing over range 10 -- backing up makes no sense! SM is powerful when you get into the furball, we find the Xorr has absolutely no ability to stay in the furball to start with. One player I respect, by the name of Zach, saw the tournament list and immediately quit the game as making his models pointless. Without the Xixx and the Xaak, he found no combat ship in the fleet worthwhile in the slightest. We have tried, without success, to change his mind, by either example or argument. Only scouts have since made the cut. He, sadly, sold all his figurines last month, and swore off the system.
