I love topics like this!
The anwser is simple: don't talk numbers before Cat hits! Everything isn't scaling right... from PvP Mages / Warlocks to simple PvE mobs. Take for instance our Paladin tank the other day in ICC 10. I recall healing him alot more then I normally do. Everything's just a bit messed up at the moment.
On another note; if by "1 trash pack" you mean the 2 Sethekk Guards you find at 3 places in the instance, that's fairly normal. They've ALWAYS done alot of damage. Add that up to the lates 4.0.1 "damage mess-up" and you can figured the picture out for yourself.
