Originally the point of the Fire tanker set was that the tanker sacrificed some defence/resistance overall to get a boost in damage. "The" power of the set is/was Burn. I have played the changes on the test server and although yes you can still make Burn do some damage the fear factor makes it a death penalty for higher dps toons that group with said fire tanker. They ignore the tank and blast the other members of the team. Unfortunately this is the exact opposite of what a tank is "supposed" to do in a group. The whole point of having a tank <of any spec> is to be the meat shield. How they get around to doing this varies from set to set.
Since Burn needs to be changed instead of leaving it in the current format change it entirely.
Make it like a fire bomb that sticks to the targets with dot damage.. heck make the mobs run amok on fire - thats ok as long as all the damage is being credited to the Fire tanker as agro so the rest of the team doesnt get hosed.
Make it like a heavy damage fire aura - end heavy and BBQs everything around the tank but drop the Dot component and fear <like a Fire sword circle>
Make it use end like Repel or Whirlwind where every mob in range gets toasted but also uses up end.
There are many things that the power could be made into besides a Fire tankers Immob. protection/group ganking power.
