Many comments below based on having vast sums of influence available.
First, get enough defensive set bonuses to hit 45% defense to melee, ranged and AoE. Next crank recharge as high as it will go. One reason is that your top DPS chain, Head Splitter -> Hack -> Disembowel -> Hack, only becomes gapless at +304% recharge. You're not going to get there, but it becomes the top chain before you're gapless. In other words, every bit of recharge you add will add to your DPS. Another reason for recharge is to double-stack Active Defense to get high defense debuff resistance. Another reason is so that you can use Shield Charge as often as you can, because seriously, Shield Charge. You'll also want some hit points, but you can usually pick up quite a few without a strong focus on that.
For endurance, the usual, like make sure you slot sufficient endurance reduction in attacks. That can be tough on a top end build, because you'll probably be running purple sets in Hack and Head Splitter for recharge, and endurance on those is bad. And while you only need five from those sets, you should use the sixth slot for the Achilles' Heel proc (Hack) and the Fury of the Gladiator proc (Head Splitter). So you're going to burn endurance like mad with your attack chain, unfortunately. So I think that sticks you with the Body Mastery epic and Physical Perfection to add a little (Edit: Oh, duh. Conserve power with your massive global recharge will cover the rest of your needs). Put a Performance Shifter proc in both Stamina and Physical Perfection, and at least slot Stamina decently. Make sure you grab the Miracle and Numina uniques. If possible, try to get sets with good endurance reduction in your other powers.
Mind you, this is all just educated guesswork. I haven't tried to put together a Broad Sword/Shield Defense build. But that's the basic outline of how I might approach it.

thanks that helps out a ton
For set bonuses what is the most important ones to get, i have just single origins slotted right now and can farm pretty well but would love to know what makes it faster, i can already tell endurance is a tiny problem and right now my Alpha slot is recharge. Any suggestions?
