Without context it's really hard to answer. You should post your full roster.

That said, Jorrg, Warmaiden, Jotun, Rector Drath, and Tayrel will all likely be useful in some place or another.

Tayrel most of all, followed by Rector Drath and then Jorgg. Kallia is better after the buff she just got, and I'd build her long before Jotun, who I think is chaff...barely even good enough to be food.  With Tayrel around for AoE Dec Def I wouldn't bother building Warmaiden.

Tbh the only reason I even mentioned Jotun is because I still use him for the DT hard secret rooms requiring HP champs, and on my DT hard scarab team :)
