In my humble opinion you have two off-hand options for warriors with the new skills and energy demands....
1] TANK - Mighty Shield of Crowns: same as before but don't skill attack, skill defense only, otherwise energy loss is too great.
2] DPS - Off hand golden bodkin of spirits, means you can skill attack all the time with no loss of energy and it still regens health, albeit not as much as shield, but it does speed up the kills.
Like i say in my opinion and it works for me. The diamond off-hands are good (hit harder and faster) but they don't regen anything, which makes them less favorable in my eyes... and the torso, legs and helm help alot.. Loving the update, just can't play enough to level dam it....lol
