And made Custodier Lts suicidal. /hyperbole Edit: yes, I'm aware that you can run them effectively. But you need to be extremely cautious with how you do it.
I think my issue with HI LTs is that I want to move my heavies forward and get a return on that point cost. I don't feel comfortable doing that with my LT. CoC would change that entire dynamic, and I plan to run a Brigada LT in StarCo. In Nomads though, I'd rather take my chances with the Interventor or some other choice.
This is where Free Agent on the TM is a godsend. He's a T3 Rambo or a T2 desperation piece. But the rest of the time you leave him in your DZ preventing Raoul / VZ / Speculo's etc from killing your squishy 'Lt', so they instead try for a risky KHD play. Muhahahaha :) Then in the end game he's got the ability to fight pretty well any 'low/mid-tier' combat piece going. Sure he can't take a Swiss, but he can clear things like Foxtrots/Hardcases on suppression to either claim a zone himself or open the way for T3 button pushes. Admittedly, I usually do what @DaRedOne describes and get aggressive early with him. But when I actually play cautiously, he's been great.
One way I play a Gecko is as a T3 force that is hard to stop. Although being a specialist helps a lot with that having a good gunner is also something valuable. T3 is usually the game deciding turn don't neglect it.
Really it boils down to how comfortable you are with losing your Lieutenant and how effective you are at prioritizing what needs to get done in a turn. I'm really not all that afraid of loss of lieutenant anymore thanks to always seeing Van Zant and Speculos on the table. I've lost a Kriza Lt first turn and come back, ramboed a Taskmaster up the field with his Lt order on Turn 3 to get points, and hid an Interventor prone on a roof and still lost him. Nothing is safe in this game, you just need to know how to deal with it when you lose something. If you haven't tried taking a Kriza or Taskmaster Lt, just try it! If you come back 5 games later and tell us that you hate it, ask yourself why? Is it the fact that it's a Lieutenant profile that makes it bad, i.e. your opponent made it a priority to murder it, or was it something else about the profile that didn't work for you? I run the Interventor HD+ Lt a TON. I've started taking the Kriza and the Taskmaster more, and it's 1) been fun to try something new 2) forced me to think carefully about deployment 3) made me think about how to use solo HI effectively, especially with a "free" order and 4) just rounded me out and made me a better player instead of always relying on an Interventor all the time. TL;DR: Try it, let us know how it went!
I use both my Kriza and taskmaster far too aggressively to use them as Lieutenants. They are priority targets for your opponent and he will usually make a beeline for killing them on turn 1, before they can wipe the floor with his forces.
Kriza lieutenant- no. Just plain NO. That's #1 priority target for your opponent (assuming you have taken HMG option). I lost him as a LT so many times.......... so no. If you have Kriza and Interventor LT - opponents 90% goes after Kriza. And if opponent succeeds you lost your best gunfighter and a LT at the same time. On the other hand - Taskmaster lt is not a bad option. Used it several times in LI lists in my Bakunin. Key here is to have several offensive options, so you are not forced to Rambo your LT. It's very fun to run 2 SWAST Red Fury + full link of Riot Grrls. And thanks to Koalas, Pulzar and other stuff, things like Friday or Speculo might not kill him, and they won't survive pulzar(or MA1 DA CCW) + Koalas combo
I rate him as an Lt I'm BTV. With a second TM buddy it's an efficient way to get a lot of points out of your DZ and a lot of midfield control into the midfield. He's also robust enough that he can survive anything except a concerted assassination attempt / bad luck / poor positioning. Which your opponent shouldn't have enough orders to pull off. Also at BTS6 2W you can get away with leaving him in your DZ if you absolutely have to.
