Rage skills almost useless for Soothsayer?

[Nevar]

So I have 7 of 9 Rage Skills unlocked and so far, I don't really see any rage skills that would benefit me when I eventually restart and play a Soothsayer. I mean KB:TL had Soul Drain and Glot's Armor, at least. CW gave us Mana Accelerator and Ball Lightning.

So far, the only skills that might be good on a Soothsayer (imo) are Christa's Gift and Regina's Messenger, which can both keep the rest of your units safe. Your thoughts?

I could just be blind here.
