Superior build(s) for Spellforce 1?

SF3 has rekindled my interested in playing through the series again.
I don't want to cheat, but I'm also not interested in flailing my way through the Spellforce 1 trilogy all over again.
So I'm looking for builds I could use for my characters in Spellforce 1 that are as strong as possible both for partying and waging war. Stuff that's really just brokenly good if possible.
