1. If you intend to PvP, which you might late-gane keep both.
2. If you team with Trollers who are prepared to help with immobs and understand what you want to achieve take Burn over the frankly naff Whirling Hands.
3. 3x Dam 3x Recharge.
I suppose it would depend on your team build. If one of those controllers is a kinetic, you'll rarely be below the damage cap in which case the "build up" powers would be superfluous. I'd certainly drop Firey Embrace first, since Build Up recharges faster and buffs your EM attacks better.
I don't have a fire tanker (yet) but the damage numbers on Burn look fantastic. If you'll always have a troller that can stop the mobs running from it, I'd say try to get it into your build.
IIRC Tanker Burn is getting a slight recharge buff on test (bringing it into line with Brute Burn) so I'd go with 3 Damage SOs, then recharge. I assume it's still autohit (or very, very high accuracy).
I've a Fire/EM tanker planned, which will be skipping Burn and taking Build Up/FE, but I'm a regular soloist so I'd not be able to use Burn effectively but would usually get full use from the +damage buffs.
Hiya
My Fire/Energy tanker is now on the post-40 run and I've really enjoyed playing her.
First off, I'd like to thank all those who post their advice here. It was most useful.
Secondly, I am now at a stage where I am think how to round off my character.
I team a lot with the same people and ALWAYS have access to a controller.
At 41, I took Fiery Embrace for the two build up combo (either using one after another for a +ACC ++DMG attack or just for the general prolonged increase in damage, which is more useful for Blazing Aura).
I will take the Energy Epics after, as I think Conserve Power will aid dramatically in my energy usage (Total Focus and Energy Transfer are HOGS!).
Here's my dilemma:
1. I've got Fiery Embrace and Build Up, which I took to take advantage of the Fire set. Its good but I wonder if I've wasted a power slot having both?
2. Since I team with 'trolls pretty much 100% of the time (I NEVER solo), would it be worth swapping out Whirl of Hands for Burn OR swapping a +DMG power (either Fiery Embrace or Build Up) for Burn?
3. What would you slot Burn with?
