What happend to the DPS?

Im not talking about the dps classes , i am talking about what did molten to do the raider dummy's? I am doing like 5-7k less dps then yestarday.

Yestarday with my druid feral i was doing 28k in burst (trink, zerk) today i cant go past 22k and after burst my dps drops to 16k
Same with my frost dk , yestarday was doing 18k (he is mostly full vicious) and today i cant go past 14k in burst then drop to 11-12k steady.

I only tested my dps on the raider dummy in the hunter trainer area in orgrimmar.

Did molten have an update or something? Did they increase dummy armor? i will go test on every dummy in orgrimar and see if there is a change.

Iv noticed since about last week my fire mage dots sometimes fall off the dummies.

I heard it's bugged but I didn't tested it yet

My huntard can dish out 30k on Raids, but on dummy my max is 22k with all of my CD's Popped, my warrior alittle 20k but in dummy i can only do 11k,..
