I use Chosens too, in a 5 men/5 Plasma configuration + Preferred Enemy (the Crimson Slaughter thing).
But the problem remains.
The kit for the Chosen is actually terrible.
1 with two claws (which is the worst, since there are no discouts)
1 with a mace
1 with an axe
1 with a powerfist
2 with a regular bolter
That minis are very good, but there is no way to play it as it is, the only possibility is to convert other minis, like we did.
I see the same problem with this Wulfen if they happen to be a similar snapfit kit, like they seems to be.
