Actually holden I have, they are too gimmicky for me, I want something that can survive and kill in many types of battles, not just geared towards one opponent type, or people who don't know what is going on.
AotL Dark Aura builds are:
Enchantment heavy offense.
Enchantment heavy defense.
Touch range.
Sacrificial Damage, which has to come quickly or the build doesn't work.
I played with the build when it first started seeing much exposure, I stopped after I realized it doesn't work at top damage versus anything but warriors and stupid/inexperianced/unaware casters.
It has its benefits, the enchantments it relies upon let you still take a moderate bit of damage while still chaining out Dark Pact and Touch of Agony.
But anything other than unfocused or off target Aura type damages will start to cut into the health pool too deeply to allow maximum casting of spells.
And degen? Well, I assume you have played against or with an invinci-monk who thought they could use their build in PvP.... Unavoidable death with any sort of attack on top of the degen.
And enchantment strippers? Well Good Game Necro... You have to re-cast because your once good damage is now only slightly annoying and not fast enough to be overly worrying. And then because you were already stripped are being babysat by a mesmer or interrupt ranger or you are dead from spike.
So yeah. Been there done that. Been killed and then killed everyone of these I've seen there-after (except when monking of course)
