Mandragor Synergy.

I have my own variation of a [[Fevered Dreams] build tailored to fit 3 heroes no matter my prof, because it only takes 3 spots, I can rely on the rest of the team to hit the mobs enough to make mass dazing useful.

I agree the AI does not handle it flawlessly but the use of AoE gives me a better chance of actually hitting the foe that needs to be hit.

[build prof=E/Me name="Hero - Flash Fever" Ene=6+2 Air=11+4 Ill=12][Power Return][Fevered Dreams][Glyph of Lesser Energy][Blinding Flash][Phantom Pain][Shock Arrow][Shrinking Armor][Resurrection Signet][/build]
[build prof=R/W name="Hero - Bigheaded Ranger" Exp=10+1 Mar=11+2 Wil=10+1][Distracting Shot][Broad Head Arrow][Savage Shot][Troll Unguent][Apply Poison][Sloth Hunters Shot][Flail][Resurrection Signet][/build]If I happen to bring [[Ulcerous Lungs] I switch [[Sloth Hunters Shot] for [[Screaming Shot].

This last one is only here to cause burning, and its main function is to hex as many foes as possible with [[Mark of Rodgort] but it is pretty good at exploiting the AI too.
[build prof=E/Ri name="Hero - Hex of Heat" Ene=6+2 Fir=12+2 Wat=2 Ear=11+1 Res=1][Mark of Rodgort][Savannah Heat][Glyph of Lesser Energy][Eruption][Maelstrom][Ward Against Melee][Ward Against Elements][Flesh of my Flesh][/build]I myself use [[Enfeebling blood] if you don't switch out [[Maelstrom] for [[Ward of Weakness].

=====================================

Scrapped builds for this are

This was the start of what I now use as my hero team build, I came up with it when I thought it would be nice to have a [[Psychic Instability] interrupter that maintained [[Glyph of Immolation] on himself.[build prof=Me/E name="Hero - Burning Fever" Fas=3+1 Ill=11+2 Air=11 Fir=8][Power Return][Shock Arrow][Fevered Dreams][Glyph of Immolation][Phantom Pain][Blinding Flash][Shrinking Armor][Resurrection Signet][/build]Switch [[Shrinking Armor] for [[Enervating Charge] if you need to add weakness.
I don't really remember why I scrapped this one, looking over it it might be energy management,


[build prof=Me/Ri name="Hero - Dream Shader" Fas=2+1 Ill=10+3 Com=8 Res=12][Shadowsong][Fevered Dreams][Phantom Pain][Weapon of Shadow][Spirit Light][Mend Body and Soul][Death Pact Signet][Life][/build]
This build worked quite well in unlocking the skills for the others when I played it in RA (with [[Life] Swapped for [[Recovery]) but with large mobs and especially when used by AI it has a problem aiming the blind onto the fevered mob.
Mobs fortunately are less interested in killing the shadowsong spirit.

[build prof=A/Rt name="Hero - Temple Strike" Dead=11+1+1 Dag=9+1 Crit=8+1 Com=8][Leaping Mantis Sting][Temple Strike][Twisting Fangs][Signet of Deadly Corruption][Sadist's Signet][Signet of Malice][Sundering Weapon][Augury of Death][/build]
What about this kind of Assassin - it is the same as i posted on HB builds forum, but it does nice conditions
Zealous Daggers are must.

Temple Strike sucks, 7 seconds of conditions with 13 seond downtime for 15e... no thanks sorry.

Wouldn't it help to have another mesmer (or someone who can spare an elite slot) bring [extend conditions]?

I'd think that extending the conditions means re-applying them with a longer duration, which means that a) you can keep those nasty conditions like Daze and Blind on your target for so much longer, and b) since the conditions are re-applied, they're re-sent to everyone in the area, due to fevered dreams, giving everyone that longer duration.

Also, it can be used to give mass-burning, if used correctly. [searing flames] has a 7 second burn time at 14 fire. If you are fast, and extend the condition to 14 seconds with a 14 spec inspiration, and you can keep up the burning indefinitely.

Lots of burning can also be attained through [burning speed], although it requires your frontliner to spec into fire. I guess a conjure/cripslash could do the job, seeing as he's already speccing into that.
