Is black plate worth it?

[CUnknown]

Sombre, I guess I am saying that even if the Black Plates didn't do better in terms of kills/losses against the heavy cav, I would still prefer them to the chainmail guys. Because I believe that they would last longer against the cav, in terms of rounds, before they broke. Honestly, that is all I care about, their use as a meatshield. I'm never really expecting my black plates to actually be my damage-dealers.

Edit: But, I should test this to be sure. If they didn't last longer in a meat-shield situation, they would for sure be totally worthless.
