Being in a cabal at all was IMM/Leader appointed. And cabal skills were completely revamped for 2.0. 1.0 Warmaster/Savant skills were madly overpowered compared to the others. I wasn't kidding when I said I've seen a (normal) Warmaster warrior throw six unspeaks in one round of normal combat. Savants, on the other hand, had counters to this ability, and other impressive boosts more tailored for mages. Communers weren't Savants then, far as I can remember (though I could be wrong on this... was a while ago), but DKs/vamps could be. Knight/Chaos abilities were more tailored to fighting each other, but on a whole were weaker than Savant/Warmaster. Justice guards were a bit stronger, but not enough to counter Warmaster/Savant skills.
Of course, Conclave powers ruled over all, but... that's a whole 'nother story.
