This has been my most successful build. It comprises of just jamming 2HR1 with the buff. Your power output is massive, you stunlock easily, and your poise is so massive you want to trade every hit. Once someone gets hit twice in a row its all over - no chance to toggle escape cause its only a 3 to 4 hit death. Not my favourite build because of its straightforward and limited playstyle but constantly winning was quite rewarding for a while.
Watch out for people who know the block parry.
Don't worry about only 30 dex. By putting it into faith the buff triples the damage of the weapon alone. And fights rarely last longer than the buff.
