That said. Mark them if you need to. Don't hesitate to tell your group to chill out with the aoe off the bat or just let them know the only one you plan on taunting off of is the healer. Do what you gotta do till you're comfortable.
Charge in, Thunderclap, take a step back, Shockwave, tab-cleave...Thunderclap again...alternate Conc Blow and Shield Slam on targets you have the least threat on and focus targets...T clap and Shockwave more when they're up. Keep cleave up. think that's it?
