WAR issue

I dont know if its just Warrior or other tanks as well but after the hotfixes this morning I went into Smileton dungeon and was getting hit waaaaay harder. I have ran this dungeon countless times and yet this time I was getting hit once by a single add and half my health bar would go down. I popped all my CDs within a matter of 10 secs to attempt to survive the mob. Bloodwhetting practically did nothing. I died. Tried the pull again and died again. I was running it with some friends (friends I have ran this dungeon at least 100 times) and they too noticed something was off. The healer mentioned he has also had issues healing WAR this morning but was fine before the hotfix. Anyone else experience this? I am just confused.
