Anyone hit by a 9-12k smash has a serious serious armor problem. Smash was literally nerfed. They flat out said it. Read the warrior post from the front page. Damage was taken out of smash and put into other abilities. My best, absolute best smash at lvl 55 was for about 8.5k.
The average is much closer to 5.5k, but the reality is with so many shielded players I see many more 3-4k hits. People seem to be getting alot better with their knockbacks and about half the time I jump to someone I am knocked back before I can smash even though I am spamming it as a jump because of the gcd.
There are many ways for sooo many classes to completely shut down a warrior. Despite the damage reduction of smash (Bioware's words) it still does ok but while in a typical Voidstar I will be somewhere around 3rd to 6th on damage. Pre 2.0 I was pretty much always number one. Now that spot is usually taken by a Sorc. or a BH.
