I have played about 10 or so games with Lucius so far, and some of them went relatively well, but most of them have seemed somewhat hopeless.
The biggest problems I've found are that Lucius, being completely dependent on his crew, can be severely limited by taking out his best Issue Command targets (mainly the Austringer). Also, I've found that many of the models preform rather mediocre when not being commanded by Lucius. The model that comes to mind the most is the Guild Guard, but you can't really bother using Issue Commands on them when you have Austringers out.
It seems that how the Austringers preform is relatively dependent on how the terrain is. If there is impassible terrain in range of where the rest of the action is going to take place, they can just hide and shoot birds at you all day long, but if not, its hard to keep them protected, especially with how weak they are.
The other models that can be taken have never been nearly as productive as the Austringers are.
The Captain can hit relatively hard and accurately, but suffers greatly in speed and range. Also, for his gun to do adequate damage, he needs a high card (11+)for his damage flip, yet Lucius himself is also dependent on those high cards (8+), so most of the time I feel that after cheating my Issue Commands, I don't have enough high cards to use for my crew.
The Guild Guard, have just never really done much for me at all. They have average speed, and decent range, but they don't really have much going for them, especially when an Austringer is only one point more. Their Armor 1 is helpful, but with a atrocious DF 4, most (if not all) attacks are going to go through, taking done their 6 WD like its nothing. They have decent melee skills, but their shooting CB is pretty terrible.
The Lawyer has the same problems that the Captain has. He's slow, and he's dependent on the same cards Lucius has, and in order for him to operate to his full potential, he needs to stand still, which means he'll most likely be relying on a Reinforcements in order to get where he needs to be. Also, he's and expensive model that completely defensive. This helps with the relative squishyness of the crew, but takes away from the offensive power, and since Lucius doesn't have much in the way of heavy hitters, this is a problem. Also, his abilities themselves are situational. Censure is dependent on how Control Card dependent the enemy is, and Cross Examination is obviously useless against a large portion of the crews.
Lastly, there is Ryle. Ryle, despite being a model immune to buffs in a crew based around them, is always one of the, if not the highest preforming model every game. He seems to go perfectly with Lucius, since Lucius' ability to Issue Commands is limited, and Ryle is a model who is more then capable to preform adequately on his own. He's a rather fast model when you take into account his Socially Repressed, and since this is usually all you need to get into position, he'll be making three attacks almost every turn. Not only is this aspect of him good, but he's by far the heaviest hitter out of the available models. His gun, which being average in CB, has excellent range, and can do massive amounts of damage in a single shot. Like the Guild Guard, he suffers in DF, but unlike the GG, he has the wounds to offset this.
Generally the core of what I take in 35ss games is:
Lucius
2 Austringer 10ss
3 Guild Guard 12ss
Ryle 8ss
Leaving 9ss to play around with. Generally I'll put in one of the 7ss models (Captain/Lawyer), and 2ss in the cache, or take the Governors Proxy. While in theory having a fourth Issue Command seems nice, he again suffers from Lucius' card hogging.
In games, the games themselves seem very rock-paper-scissors-esque. Seamus getting Treasure Hunt with me getting Assassinate seems almost impossible, due to their speed to get the treasure, and Seamus' Hard to Wound completely neuters my damage (as almost everything I has requires Severe damage to actually matter). Another difficult match up is the Viktorias, regardless of strategy. They are all so fast, and hit so hard and accurately, they can just tear through all of my models with ease, especially Misaki and the Viktorias themselves.
I have recently realized that I am not utilizing the utility of the crew to its fullest (in fact I didn't even know what Halt! did until the last game I played), but I don't see how using all of these utility abilities could have a significant impact on the outcome of the game. Cordon is difficult to go off, and requires my weakest models to go out in front. Halt requires me to hit with a model that sucks at shooting. Menace requires me to sacrifice doing other actions with a costly model that can actually hurt things on its own. The Lawyer requires me to sacrifice damage for situational utility that depends on the same cards Lucius does.
tl;dr I have read just about everything posted about Lucius, but I still can't see how to fully utilize this crew. Its full of easy to kill models that are dependent on one thing or another. I understand that its in no way a straight-forward crew, but it just seems to have many weaknesses, and no strength that stands out very much, if at all.
Also, I apologize for the massive wall of text, and very much appreciate anybody who actually reads it.
