I beat the second to last Nightfall mission on my ele the first time with henchmen and heroes... but just barely. And I didn't use any of the normally suggested skills.
However, on my warrior I have tried it over 20 times with just heroes and henchmen and never beaten Shiro... er impossible odds rather (because beating him is easy, but beating his skill is... impossible [bad joke I know]).
I've split the heroes up so that impossible odds can't hit them all at once. And still, I end up with 60% DP by the end, even when I go into the Shiro fight with none.
I have tried Wild Blow, Throw Dirt, henchmen with blinds, SS and many other things I don't recall any more. But that's not what's important.
Now, my warrior is maxed. Made him about a month after Prophecies was released... He's got greens, golds, perfect gear... It seems to me that there should be a way for my warrior and his group of henchmen/heroes to do this mission.
As far as I see it, I now have the following choices...
a) Spend eight years getting a masters in GuildWarsology so that I can easily beat the mission blindfolded, hanging upside down above a tank of blood-thirsty sharks.
No thanks. I'm a bit more casual a gamer than that.
b) Resign myself to the idea that I will never beat Shiro just using some henchmen, heroes and my own wits and wait a hundred years for someone to develop a cybernetic brain that will allow me to issue orders to my hencmen by thought alone.
No. Ever since I watched Johny Pneumonic, I really haven't been a fan of cyborg brains.
c) Hope that someday someone at A.Net will get around to nerfing "impossible odds".
No. I don't think that's very likely to happen; impossible even. (If I had a lisp I might call it inconceivable but then I'd probably fall over dead a moment later and Fred Savage would be there with Columbo and then I'd have to kill myself... again.)
d) Play the mission until I get really, really, really lucky.
That's most likely, the only choice I have. At least I'll have something to do with all of that free time I've been wasting at the food bank handing out groceries.
But that's not the reason I'm posting. I just wanted to write all of this up to make this one almost completely unrelated point...
In all of Guild Wars, through all of the missions through all three campaigns, this is the first time that my elementalist has solo'd (with hench) any mission better than my warrior. And though I feel that it was most likely purely luck, and that feeling robs me of any real pleasure I might have ever derived from that knowldge, thank you anyway A.Net.
Due to the implimentation of this unreasonable skill, my elementalist (sometimes called a lemmingist) is finally better at something than my warrior is. (Excluding the ever prestigious duty of carrying flags around and spamming group heals of course.)
I know you probably didn't mean for any of this to happen A.Net, but it really makes me laugh. The irony of this is truly amazing. Seriously, I'm having a good time with this. I can't think about it and not start cracking up. My side hurts now.
P.S. This post is not about game balance, skills, builds or anything else along those lines. So please don't misconstrue it as such. And please, if you post in this thread, don't tell me how to beat "impossible odds" with my warrior. I would like to bask in utter uberness of my elementalist for a while longer.

-EDIT-
I invite others to share any similar humorous (or ironic) experieces that they may have encountered.
