The usual method for grouping is dual wield, however with changes to aa there is a large gain in the dps using a sword and board, I personaly haven't parsed the results, but I am informed by a few of raiding friends that the sword and shield is at least equal if not better dps than two weapons and reduced damage incurred. That said in a grouping layout it will for all intensive reasons probably not matter.

As for weapons and armor in the end game it is pretty easy to tell look for the greatest ratio you can 20/20 isn't as good as 21/20 etc. As for Armor and Heroics it will take a bit of a play style for you to pick up but I am an armor over hp type of guy so I like the heaviest AC I can get which means I am also agility over stamina. I know many people out there may not agree with me so I will include some people prefer hp to ac or in moderation so that would mean balancing hsta vs hagi if possible and getting a more balanced ac / hp model. The same holds true for my aug choices I prefer 35 ac plus augs with hp if possible however in some circumstances I have been known to use a +endurance no hp aug for short term while camping other augs.
