I'll say moot on the S2 T2 because the auto-wound on 2+ and no-armor-save ASF sword. Trade-off of styles.
With one attack. If Teclis's block gets into combat, he's done if he's in the front rank. All someone has to do is target all the models that can hit him to do so. He is much easier to kill then your standard
lvl 4.
He hits like a sock full of 2nd Edition Dreadnoughts, but a stiff breeze will break his back.
