Excellent work!
As of today I was thinking on how to use squats in 40k. Now I have the answer - your list! Of course I've got some comments and/or suggestions but I want to start to say that I like the list very much indeed and of the things that I don't bring up below, I'm very happy with and should remain as they are... if you ask me that is.
And I have seen the RT-list for the squats (by courtesy of Mr. Rasmus) but I've never played with or against any type of squats... so maybe I don't know the real flavour of the squats. But I'm not going to let that stop me. And if I explain something incoherent or need to rephrase my entry, just tell me and I'll do my best. But I'll be very picky...
Rapier L.Destroyer
Don't need str.10 and AP1. The long range and 2d6+9 will do quite nicely I think. It'll make it a badass lascannon instead of a badass railgun.
The blast tips
I don't know... they're OK as a concept, maybe a bit inexpensive. The incendiary needs a some clarification though. Can you use all six templates on the same spot? Perhaps they can't overlap or something... the roasting delivered by six heavy flamers on a single unit (if possible) is not to be underestimated... Personally I'm quite fond of flamers but that's of topic... Otherwise it seems like a good idea.
Conversion beemer
OK, don't change a thing, it's perfect! OK maybe the AP1 to AP2 so that nobody gets confused as to the glancing hit caused by a AP1 weapon gets converted into a penetrating hit. Minor detail though...
Power field
Maybe it should be one per army? It's pretty darn good... maybe not though, as only the HQ's can have it.
Mole mortar
Really like the different burst-types reflecting the capabilities of the shot. But... I think that "only" glancing hits from a mole mortar would be better, brings it in line of being more of a infantry killer than a Land raider hunter. It also fits with the minefield rules (glancing only). So my proposition is to make 4+ glancing hit, which is pretty good against heavier vehicles. Make it a bit more expensive as well perhaps 15 pts? Since it got extra capabilities not just killing power.
Tarantula
I don't see why it has to have a d2 shots. Twinlinked is really good as it is. I agree that the d2 doesn't do much... which for me is another reason for it to go. About points costs... round it to more even numbers! Such as 15, 20 etc. just cause it looks nicer
And make the missile launcher cheaper. Make it the same points as the lascannon?
Kinghand and ancestor
They have str. 5, make it str 4 That make their str. upgraded in the same manner as an ork warboss.
Ancestor psychic powers
Fun and different powers. A good mix. Perhaps you want to up the domination a bit, since 5 pts is... very inexpensive for a great power. The effects of pinning are great and especially since there's no way to protect youself from it, 5 pts is a bit to little, maybe 15?
OK. I'm finished now. I don't want to give you the wrong idea here, because I think it's a very solid list. Much better than the lists I tried and failed to produce some years ago. Maybe there's reasons (most likely knowing Rasmus) as to why the list as it is and maybe I agree with you once explained as to why you've made certain decisions the way that you have. Well good luck and I hope that perhaps
some of my suggestions helps you perfect your your fine piece of craftsmanship (I'm talking about list...).
Keep up the good work!
