Be careful about whining. I'm not doing a full infraction because there was useful conversation that followed, but your initial post is just a giant ball of WAHH.
My experience so far on beta have been disappointing. First, my rip ticks are normally 900-1000. Mind you I'm in mostly all BiS gear from live and there wasn't much in the of leveling upgrades since itemization was incomplete a couple weeks back. In either case it's disappointing to see that at lvl85 in beta on a lvl60 training dummy, I'm doing less damage than I do on live at 80 on a 83 training dummy.
In regards to tanking, rage sucks, always raged starved. Like others are still trying to figure out, I'm still unsure about how to optimally use pulverize.
