The purpose of the build is to provide 53% dmg reduction from 2 or more clumps of monsters for the majority of a fight.

Anthem of Flame

Energizing Chorus
Glowing Signet
Fire Attunement
Leader's Comfort/Rez
Equipment: Fire Staff or Fire Wand/Fire Offhand or +5e Furious Spear/Fire Offhand. I prefer furious spear of enchanting for the faster attack speed which provides more adrenaline.
Start with Fire Attunement and then use Searing Flames which will set foes on fire for 6 secs. You will gain 6e back from Fire Attunement - net loss 9e. Find second clump of monsters and cast SF on them - now down 18e. Toss spear twice, then use Anthem of Flame (gains you 3e). Use SF (9e) and follow w glowing signet (16e gain). If you're doing the math, you're only down 8e (not counting e-regen). Use SF on another clump of monsters (9e). Toss spear until GFTE charges, then use it (gains 8e). Use Energizing Chorus when charged (8e gain), then use SF two more times. Keep ToF on at all times (only costs 2e). Use Anthem of Flame (3e gain).
If you do this correctly, you should have no energy issues whatsoever. If you mess up and spam SF w/o gaining adrenaline, you'll get low on energy. Charge up adrenaline then, use GFTE, then use Enrgizing Chorus, then Anthem of Flame, which as a chain will gain you 23e. Use SF and then Glowing sig and you will have gained 30e. As you see, you can go from 0e to 30e in a matter of seconds

There's some challenge to running this build b/c you have to use SF on high dmg output targets while keeping your heroes/henchies focused on the soft targets such as healers. Once you have one clump of monsters on fire, you have to switch to another and get them on fire. So there's a decent bit of target switching for casting SF, while keeping your spear throws targeted on the soft targets. Also, the e-management takes some practice. Use GFTE before Energizing Chorus if both are charged. Never use GFTE right after Energizing Chorus as it wastes the benefit of the latter. Use glowing sig only when your energy is pretty low. Don't cast SF on a clump of monsters already on fire as this won't renew the burning.
This build may seem awful at first glance b/c it uses an energy intensive elite from another profession and the para only has 2 pips of e-regen. And we all know that an Ele can put out far higher dmg than another prof using Ele spells. However, the purpose of this build is not dmg, it's to provide fairly constant protection.
Incoming is thought to be a great elite b/c at 16 Command it provides 50% dmg reduction for 7 seconds. However, it has a 20 sec recharge. So for about 1/3 of the time of a fight, it provides very good dmg reduction. This build can provide a 53% dmg reduction thanks to ToF, while being active more than 1/3 of the duration of a battle. While Anthem of Flame and Burning Finale can also provide some nice burning (and thereby protection), the problem with them is that they usually only affect the clump of monsters that the henchies/heroes are focusing fire on.
With the Searing Protter, you can have your henchies/heroes go after the soft targets first, which they will set on fire thanks to anthem of flame, while you are free to use SF on the melee types and rangers that attack your casters. There's no way a hero can run this build right, unless you micro-manage like crazy, in which case you may as well play it yourself.
I find it to be a great build if played right. Sounds weird in theory, I know, but pretty effective in practice.
