I will say that if you want a second
HQ choice of a pair of Leman Russes, the Vanquisher + Exterminator combo is actually very effective.
Your Tank Commander is in the Vanquisher, hull mounted Lascannon too of course, and I typically throw a pintle mounted weapon on there too to help it not be a 50/50 loss of the main gun on a weapon destroyed result.
You then attach an Exterminator with a hull lascannon and hunt armor at 48" or closer. You can split fire if need-be, but most of the time any armor you point this squad at (assuming it's not
AV:14) is going to have a bad day provided it's inside of 48" (and really, rarely are you going to have a target at further than 48").
Your Vanquisher gets a pair of
BS:4 anti-tank shots in the form of the main Vanquisher cannon and hull lascannon, and then you follow that up with 4x twinlinked autocannon shots and a second hull lascannon at
BS:3. I've had this squadron completely destroy a vehicle a turn, every turn, and they can split fire order too, so you can hit multiple targets if need be.
I agree that Pask is better served in a Punisher, or Exterminator, or even an Executioner can be fun some times. But don't discount the humble Vanquisher and Exterminator combo, especially if you know you're going up against some armored targets. They make a nice long-range platform for dealing with hard targets.
Just adding my thoughts on that. Take it easy for now.
