If you're planning on team tanking, the only changes I'd make would be to drop Build Up, Resurgence, and Strength of Will(or Hasten), and pick up Char, Fireblast, and Fireball. I also have Bone Smasher in my build. Leaving me without Build Up, Resurgence, Strength of Will, and Hasten from your build. Strength of Will was the most difficult to leave out. The extra AoE in Fireball helps with agro management immensely, however.
With Fireblast, Air Superiority, and Bone Smasher recharging fairly quicky even without Hasten, my single target attacks were always up....great for teams once again. I don't even use Barrage.
Edit: One option I haven't tried yet is to remove Bone Smasher, slot Barrage instead, and pick up Strength of Will or Heat Loss. These are probably viable options, but I rarely play my WP/EM Tanker anymore....so haven't tinkered much.
I just respect my main WP/EM tanker and I was looking for some opinions on his power selection and slotting. Before hand, he was aweful! He used only the main power sets, fitness, flight and epic energy... (He's currently level 45) I also didn't take taunt till now either! lol
After this respec, he's much, much better! He can handle mobs almost as well as an Ivnc, but better against psy an has far less down time. The only thing I'm pretty set on is Flight over Leaping on this character, it's part of being in powered armor I guess. lol
