As a fire tanker for almost 2 years, i have experimented with many variations, with all the changes that have occurred in time. Blazing Aura is now a useless power unless wanting to detect stalkers in PvP, it does very little damage and taunt is far superior to stop them from running.
Tough and weave are essential, as well as health and stamina with most tankers.
Fire Tankers are predators, more so like tanker/scrappers rather than defenders, they kill before being killed.
Gone are the days of burn, consume is worth 6 slotting and it does consume end to the full if you slot it right, 4 end and 2 recharge.
The healing flames doesn't require full slotting, 2 heals and 1 end reduction takes it to 30 seconds, which is enough for most tankers.
slot your tough and weave to about 4 each
and when you get epics look to acurracy and conserve energy
