My War/Mo build I use to make a quick buck farming those is just as good as a Mo/War. My personal record for the run is 2min & 15sec from clicking the Enter Mission button to coming back to town. But that was before I started kiting them into a big ol group before a I killed them. Now an average run is like 4min.
No, the individual drops arent really that great. Mostly minotaur horns & hides, piles of gold between 60 and 110 pieces, the odd white weapon or two with a blue or so every run. Once in a while you'll get purple items, dye, and elonian keys, and every blue moon you'll get a gold. But its easy money. The real reason the farming got so big there is because of the horn collector outside Augry gives armor and you can salvage 25-35 of a common material out of the armor. Before the release of Factions and two or so weeks after, hide and cloth prices spiked because people were wanting armor for their new characters, mainly being ritualists and assassins, which require those materials for their armor. And thus, you have people taking advantage of it. Hence the bot population at Elona.
No troll tusk buyers are inefficient money makers, its real stupid iMHO how they even waste their time doing it. What troll tuskers do is buy tusk for less than 25g(typical offer is 11-18g each, has innate price of 8) then go to rankor w/ their stacks of troll tusk, run to collector and get 15% on stance swords which are worth 125g each, which they either sell to trader and get instant 25g per tusk gain or sell to newbies needing new swords. If I were them, I'd actually take the time to clear out snake dance, instead of doing that crap, or kill the trolls themselves.
