First of all, we do not need you to link your armory. It is right there on the side for us all to see. Second of all, please do not beg for hand holding. There is a ton of information out there about this, and you should be able to understand it clearly. If you are confused, download the lastest combat spreadsheet provided.
With the recent nerf to ArP, I have noticed if you don't have mace spec or a lot of ArP from gear (400+) and/or an ArP trinket it isn't worth gemming for ArP. If anything, you would gain 4-6 dps while giving up crit and defensive stats. As always, look at the spreadsheet. It is there for a reason.
