Whats this I hear about MM's Soloing Thirsty River?

A guildie of mine was saying he's heard of MM's soloing Thirsty River, I have no idea how to do it and he can't figure it out either, is what he heard even true, or are we missing something? We have tried everything we can think of and we are stumped.

If it is true, what in the world are you using for skills? Or is it a technique thing?

I've heard this also, but im not sure how it is done : \

I can do it...but i cant really SOLO it, i need some henchies to get the ball rolling to get my minions up and after i get about 10 its smooth sailing..but i get some good money doing it..

i "rush" this mission quite a bit with my MM, its not too hard and i just ask the people i take with my to help kill the ginats and one group of rockshoots, and thats all. tbh its not terribly hard, and my only sup vigor has come from there as well. i seem to be the only euro district thirsty runner, ive never seen anyone else :P
