I pointed out that their standard battlefield tactics would be much less effective. By creating new and inventive ones, you apparently are agreeing with me.

BTW, what are the 13 individual channelers bonded to my hypothetical warders doing while your circle of 13 is obsessing about digging a bigger hole to drop these 20 warders in?

My initial point remains, C armor is better than any existing armor, the only debate that can really be had is "how much better."

Every time you bring out some world shaking action tht is stop a C armored force, you simply illustrate that point better. Look at the lengths you are going to stop 20 people with swords and C armor versus what the discussion would be without the C armor.
