I ran some simulations of a Greatsword Fighter using power attack feat and a followup attack and Shield Fighter using double slice feat and the raise a shield action. I played smart with shield blocking. I would block as long as my shield wouldn't break (unless I would be downed otherwise).
Thoughts?
In most D&D games I've been in a power striker is a better defensive player, because although he takes damage, it's easier to protect or heal a high damage dealer than increase damage for a good blocker. So one on one, sure, send the tank. For a group, three barbarians with greatswords + a cleric I think will win against thee sword-and-board gals with a cleric.
Amusingly, I'm about to test this with my first post-playtest character; a half-orc warpriest cleric. I plan to start off as greatsword using self-buff magic weapon spell at level 1 to attack at +1 doing 2d12+3, and casting shield mostly for the AC, or when I need it to avoid dropping (orc ferocity will also help).
At level 3 I retrain orc ferocity to the orc weapon feat, since then I'll have access to the advanced orc weapons (made martial by the feat, made available by level 3 class feature), and switch to that plus a shield. It will be fun to see if that's a good switch or not!
