Armory is buggy for me atm so I can't compare the stats.
However I am certain you don't have more AP in full PvP gear over someone with triple SWP 4/8 T6 and 4/5 S4.
I'll venture a guess that he has 1/3 in careful aim and you have 3/3. That's 100 AP right there. If you both used the same spec you'd see he has more AP.
With my char I have about 2090AP with viper and dual wield 30 int weapons and 3/3 careful aim (full pvp gear).
I agree that wasting stat slots on stamina is bad, but it's his char, Mega only plays it.
I don't use 3/3 Careful aim, that's a waste as it prevents going 7/41/13 with the correct talents for dps.
You have 2090 AP with socketing Agility, double your AP from gems and you see where I get 2100+ AP from with 1Hs/viper?
Even without S4 shoulders and S4 OH i'm at 2080ish with battlemaster on.
20 AP>10 agi for pure dps, so I socket AP in all reds and 10 AP 5 crit in all yellows besides one (said this earlier, many times in other threads ), and 24 AP/speed with 12 agi boots as well.
Yeah just saying because mega said it's the best geared character for arena.
I would ditch 2 pieces of the T6 and resocket that crap, but that's just what the spreadsheet says. Who knows, maybe 15 stam gem saves ya
