Crimson Fists @1500 and 1850.

CF without Kantor? Well IMHO I would replace the majority of the tacs with scouts and replace Lysander with Kantor.

I prefer to run a fluffy CF list though, I feel they are one of the few chapters that lend themselves well to fluffy army lists.

DT.

edit: I would also have as many fists as humanly possible. But that is just me.

Here are two lists I've beent thinking up. The 1500 list beat Daemons yesturday. 1850 list is theoretical, I would need to buy 5 more assault Terminators for the LC, and the two Predators. Please comment.

Well, my fluff reason behind having Lysander in there is The Imperial Fists sent their best Captain (Lysander) to aid Kantor in rebuilding the Chapter, as they are a 2nd founding and highly successful Imprerial Fists Successor chapter.

I do like power fists, I have three Sgts modeled with them, but I'm beginning to think they are too much of a point sink. Also, if you get assault by anything that you need a power fist to kill then you did something wrong with that Tactical squad, at least in my opinion and experiance.

Mostly little things that I'd change tbh...

Vortex of Doom without terminator armour is always a little risky imo and a single pod of sternguard is a really expensive fire and forget bomb (I'm not a fan of the throw away unit though so it's down to playstyle a little).

Power weapons have always felt a little like a waste of points on a tactical sgt for me, it's 2 S4 attacks that ignore armour whereas for another 10 you can hit at S8 with a fist which also stops you getting chomped by something you can't hurt. I'd also be tempted to change out some missile launcher / flamer combos for multimeltas but that depends on the level of high AV mech you play against.

For your 1850 list the assault termie mass is overkill, anything it hits is dead, your problem will be that you're going to lose a few on deepstrike. I'd strongly consider dropping some termies and possibly one of the dakka preds (although they're amazing for their points cost) and taking a LRC to deliver your assaulty death, that gives you a few more options for delivering lysander and or the libby who I would definately stick in termie armour with a storm shield in this case.

Opinions and, as always, YMMV
