So I am trying to decide exactly how to kit out my assault terminators. I plan on running 7 assault terminators with a librarian with termi armor in a LRC.
Excellent idea thus far.
I want this squad to steal objectives from hard to kill units like space marines or terminators. If they are light infantry the LRC should be able to gun them down. I wont run pure TH/SS as that just seems to vulnerable to being tied up by orks forever and a day in the event that i have to assault orks.
Also excellent plan, however, pure
TH/
SS` problem is not getting tied up by orks forever. You are looking at the difference of, maximum, seven total attacks. Attacks that wound on a 2+ against almost anything in the game rather than rerolling S4. The problem with
TH/
SS is that almost everything swings before you, and while your odds are good with 2+/3++ of lasting that long...there are days. This is not really helped by lightning claws that often (With orks actually being one of a very small group of remotely threatening
CC units that isn't also I4.) because...well...a
CC unit without at least I3+
FC is just not that common. Trading durability for striking FIRST is a viable idea. Trading durability for striking simul is at best, insurance.
TL;DR If I took anything but 100%
TH/
SS, it would only be one or two TLCs to help the librarian deal with
ICs and similar, particularly in a squad that size where a bad save or two doesn't mean quite as much. Certainly over half would be equipped with
TH/
SS.
I definitely want GOI in the event that the LRC is unable to get the terminators to their destination or to get them out of severe trouble or whatever movement dictates.
While I have had luck with
GOI and sternguard, It's a definite increase in difficulty pulling it off with 8 terminators who realistically need to wind up within 6 inches this turn. (Because lets face it, the only shooting you are going to get is from the librarian IF he has a gun or is an epistolary, and the opponent is going to back off as far as possible when you pull this move. It's very easy from here to minimize the threat an
AT squad poses by most armies, there is a reason why people take ATs with
LRs, Shrike, or don't bother.)
Null zone would be my hands down pick. Not only for sitting in the
LR and using its hull to increase the size of the bubble, but because it allows YOUR deathstar, to take on an opposing deathstar...and win. I have ran into very few situations where the enemy army did not have SOMETHING that this spell did not kneecap.
Avenger or vortex would be my other pick. Might is less than inspiring on a 2A model without preferred enemy and without a second
CCW (Doubly so in a unit full of thunderhammers, which should be taking out any high T and
AV targets with gusto) and while smite is great against terminators, it lacks real utility against anything else. Avenger however, is godlike against any exposed infantry, and vortex allows for something to shoot at the transport OR exposed infantry. Now, for the downsides:
Avenger may break a squad, yes. Ultramarines will immediately go to ground, and inevitably fail their morale check when they take 25% casualties, and attempt to regroup next turn. Don't allow them the opportunity. Get a crappy land speeder with its guns blown off, or a rhino with nothing else to do, or one of your own
tac squads, and escort him off the board. He still cannot regroup within 6 inches of an enemy unit.
Vortex may also perils and slap you with a demolisher cannon round, right on your head. This requires you to perils however, and this is anecdotal...but I have taken a -lot- of psychic tests, and I don't remember hitting perils very often. Quite frankly, with a
TH/
SS squad, even if you did you have the best chance of having a combat viable unit afterwards here than anywhere else in the codex. Terminator librarians are also the only kind that can fling this at someone and still assault afterwards.
Terminators +
LRC is always a good plan, just the decision to be made if you want some psychic shooting and support from the librarian...or if you want a
CC beatstick. If you want a
CC beatstick you should probably run a
TDA chaplain or Cassius.
