I love the idea of having 2 slann in my list. I would roll with one light and the other life, both with the loremaster, immune to non-magic, and extra power dice disciplines. I think i would give a TG unit to the life slann because of the throne of vines spell makes wiping out the TG unit with a bad miscast less likely. SO the only BAD side i can see to this is that power dice are going to be in shot supply, especially if i get bad rolls, and the two slann, outfitted as mentioned, exactly fills up the entire lord section in a 3k list, so i cant do some awesome oldblood stuff. Thoughts and ideas?
