Skrattir in wolf form no weaknesses? Have you even played with them in MP? They have enough weaknesses. (ps, I think CBM reduced the HP a bit). Sure they are powerful, but removing the hand slots really takes away they usability as thugs. 250gold is way to expensive for a unit without shields, or the ability to hold shields, or a head slot. Against any opponent even with shields and head slots they usually die like flies. (They do not have a lot of MR for example, without hand slots they are stuck at reasonably low damage and attack (for thugs/sc anyway), defense and only normal damage, not AP or AN. Which removes large swaths of jotun and urdheims midgame strategies). And without head or hands you cannot even give them enough resistances against attacks. Using them against a skilled opponent is now a big mistake.

Nobody will ever use them in wolf-form anymore. As you get more mage bang for your buck in normal form. (Fallen frost spam for example, blood gives easy access to communions).

Fear on recruitable units is a big no no. Fear is way to good massed. That is what makes the demon knights so good. The massed fear on the super heavy cav. Also the nightmare is not recruitable in the base game, and I think they have never been balanced for ingame use. (The 15 enc is a bit strange for example).

Other stuff you could try with the samurai, give them patrol and pillage bonuses. Make them auto remove unrest. (Doesn't work on troops iirc).
