Sudden Ac loss

Hi all.

I need to know if Sidd Ac is right or bugged. Last night he was sitting on 27.9k Ac. This was after the 3.1 FP nerf which took it back to 60%. I was online after the patch and the Ac had been reduced prior to my short leave.

Now last night I noticed the Ac from neck ring etc had been flatlined from any bonus. No big only got Ac on Neck. But for some reason my Ac had dropped again by 2k to 24.9k.

My base Ac before talents and FP is 15613 with the mutliplyer of 75% it should be in or round 27k+. Can some please confim if my cals are right or wrong :0) please. Because to me 24.9k with the current unchanged talents pre 3.2 is to low. Tried to get a response on the DK forums but theres no response not even a NOOB call from my trolls lmao.

Anyone who could do a quick recheck for me please would be a great help, before I start a poss gm ticket.

P.S working with my Base Ac and using old FP+Talent my calculation had my old Ac value at 29.9k. The % of Ac bonus then was 95%. 80% from FP then 15% from toughness.
