Well I will help you out on all those questions.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
A Troll Farmer!?!!!??!
Yes a troll farmer, its an easy way to get money and with this warrior build it takes 2-3 minutes a farm. But its fun, unlike other farming builds.
Trolls have crappy drops!
Trolls usually have crappy drops, but 2/3 times you farm them you find one dye, and 1/5 dyes are white, silver, or black. Just yesterday I found a Vampiric Spatha of TenguSlaying. Max. Is that crappy? I then bought a +30 pommel for 10k then put it on the sword. I am selling it for 30-40k.
What about AoE?
Well this build causes absolutely no AoE. Not once has a SINGLE troll ran away from me. I swear.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Now for the build.
My original version of the build was put on PvXBuilds, here is a link!
Mountain Troll Farmer
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
A Mountain Troll Farmer takes advantage of the Warrior's ability to block attacks, to get close to the large numbers of trolls found in Talus Chute. Then He/She uses Cyclone Axe to get his/her Adrenaline pumping to wipe out those trolls, while using Healing Skills to stay alive.
~~~~~Attributes and Skills~~~~~

~Axe Mastery~~~9 + 2 + 1
~Healing Prayers~9

~~~~~Equipment~~~~~
Armor
~Max Gladiators Armor is preferable. 3 Knights Armor and 2 Radiant Armor.
Weapons
~I use the Totem Axe, but Victo's Battle Axe works better.
~Also use the Crimson Carapace Shield.
~~~~~Usage~~~~~
Leave Droknars Forge and go to Talus Chute. Now run towards the troll caves (to your left). Try to avoid the Avicara they are annoying. Then, when your right outside the caves, and outside of the trolls Aggro, use Live Vicariously, then when your Energy is full use Mending. Now run into the caves and round up the trolls. If you have 20 energy leftover after mending then you can use Sprint to round up the trolls (not very effective) or use Cyclone Axe twice. When the trolls start attacking you use Gladiators Defense followed by Vigorous Spirit. Then use Cyclone Axe (twice if you have enough energy). Then right as Gladiators Defense finishes use Bonetti's Defense. Once Cyclone Axe has recharged use it again, immediately followed by Bonetti's Defense. Then again use Cyclone Axe followed by Bonetti's Defense. Continue this pattern untill Gladiators Defense is ready. When Gladiators Defense is ready, use Cyclone Axe, then Gladiators Defense, then Healing Breeze, then Vigorous Spirit, then Cyclone Axe (twice if it says you have 4 energy left). Then repeat the cycle untill the trolls are dead! (roughly 3 minutes).
Here is the skill order.
Sprint (to get to the caves and avoid/drop avicara/trolls).
Live Vicariously
Mending
Round up trolls
Gladiators Defense
Vigorous Spirit
Cyclone Axe
Cyclone Axe (if you have the extra energy)
Bonetti’s Defense
Cyclone Axe
Bonetti’s Defense
Cyclone Axe
Bonetti’s Defense
Cyclone Axe
Gladiators Defense
Healing Breeze
Vigorous Spirit
Cyclone Axe
Cyclone Axe (if you have the extra energy)
Bonetti’s Defense
Cyclone Axe
And continue until the trolls are dead!
~~~~~~Picture~~~~~~

All in one picture of what you need!
~~~~~~Variants~~~~~~
There are many other Warrior/Monk Farming techniques of these trolls but the most effective is this one!
~~~~~~Notes~~~~~~
You need at least 25 energy to run this build effectively so make sure you either have Gladiators Armor, or Runes to boost your energy!
I can do this farm with -15% DP. Although I have never tried it with -30% because that has never happened!
Every 5 spawns you will find a spawn where the Avicara are literally covering the entire map, if that happens, just rezone.
You get a Dye 2/3 times you kill the trolls. And 1/8 dyes are black, white, or silver. I got a Black Dye just yesterday!
1/10 times you farm the trolls you will find a good gold weapon, I found a Vampiric Spatha of Tenguslaying just the other day. I then bought a +30 Sword Pommell and am still selling it for 30-40k!
This is also a great way to power level friends! I ask for 1k per level and all the drops. If it is a good friend, just ask for drops.
Do not round up the trolls by the bosses with the first batch, you will most likely die.
This build uses only Core Skills, so anyone can use it and I am sure that you could toss some Factions or Nightfall skills in there!
