I did some testing on the test server with burn last night and at the present time I feel burn is now a power that I can skip in the Fire Tanker set. The one advantage that burn offers now is the ability to free yourself from immobilization and I can cover that problem with Combat Jumping. I understand why the developers wanted to change burn but I feel now burn is almost useless. My suggestion with burn is to change it to a huge recharge time (say 5 minutes and not effected by hasten) but make it have the power of inferno in the baster set. That way burn will be usefull as an ultimate escape power but cannot be spammed due to the timer length.
