but it will NOT be ahead of threat and you need fewer stats raise so you'll have more room for STR and CON. When in DPS-mode the S&Ber will be switching to a Two-hander.
Junt's pally can hit 84 AC while using an Epic Sword of Shadows, a guildy of mine posted a first-life pally build who can get 88 AC while TWFing in heavy armor.
I got a TWFing defender build, the damage is okay. it's not bad but it's nowhere near what a real DPS build will put out.
