Getting the most out of Hot Feet and Blazing Aura

I'm currently playing an Psy/Fire blaster up to 50 and I am planning on investing a serious amount of money into it. I'm currently level 38 and I'm wondering if I've made a mistake in taking Hot Feet and Blazing Aura. Hot Feet in particular has an extraordinarily high amount of End drain, and as my "final build" will probably have Weave, Tough, Combat Jumping and Frozen Armor all running, I don't know if I'll be able to afford it.

My final build is going to be a soft-capped S/L defense Blapper. Could someone try to sell me on Hot Feet and/or Blazing Aura? Are they worth running? Should I only have one? Am I too worried about the endurance cost? Any advice would be appreciated.

Blazing Aura is really not worth it. It has a very small radius (8 ft) so it only hits targets that are right next to you. Between your primary set AoEs, Burn and Fire Sword Circle things really won't stay alive long that close. It can help on AVs / EBs if you can manage to keep it going for long periods (Cardiac might help), but in general it probably isn't worth it... I know I skipped it on my Fire/Fire and don't regret it.

Hot Feet is actually decent though. It has a much larger area and it causes mobs to scatter (while slowed), which provides a bit of extra mitigation. The damage isn't fantastic but it can add up pretty fast on large groups, especially on targets that aren't close enough for the other /Fire AoEs to hit. It does cost a ton of endurance but I manage to run Hot Feet, Scorpion Shield, Weave, Maneuvers, Acrobatics, and Combat Jumping (plus Tactics at times) and can generally last long enough for Consume to recharge before running out of endurance. I do have both recovery uniques slotted (total of about 3 end/sec recovered) but it's not a massive recovery build... I mainly worried about softcapping S/L and getting decent recharge.

Just don't slot Obliteration in Hot Feet... that S/L defense is not worth the huge end drain because Obliteration has very little end reduction. I slotted three Dam/End IOs from different sets and an Acc/Dam/End and that works well for me... ED capped damage and endurance reduction and a bit of accuracy (plus a ton more from the inevitable Thunderstrikes in my single target blasts).

That looks like a nice slotting if you have six slots in Hot Feet... I only had four so I went with damage and endurance and ignored slow.

Er, I meant I had four slots and wanted ED capped damage and endurance... didn't leave room for any slow or much accuracy but I have a ton of global accuracy so no big deal there.

Multi-Strike Dam/End
Cleaving Blow Dam/End
Scirocco's Dam/End
Scirocco's Acc/Dam/End

95% damage and endurance plus a little accuracy (all I need with 57% more from bonuses and +6% to-hit) and a regen bonus. I could swap out a Dam/End for a Dam/Slow but this build is very endurance heavy so I wanted as much endurance reduction as possible. I may test it out though... I can always trade out the Cleaving Blow for a cheap Slow set Dam/Slow IO and then drop in another Cleaving dirt cheap if I don't like it.
