Fair enough, I suppose. I botched the very first attempt I was in, too, but owned up to it and learned from it. For some, it's like 5 or 6 tries before they figure it out or stop and listen. By then, there's another reckless newbie on the team.
The most success I've had with my W/Mo is by converting all my attribute points and skills over to monk ones, equipping a wand and focus that give me + energy (26/26) and performing as secondary healer. I usually get to about the end with that setup unless someone's really boneheaded (although I've had a couple of complaints along the lines of "what the hell is our Warrior doing? She's not aggroing").
Sorry for the vent, but it's really frustrating. I got to Amnoon at Level 16 and had some really good help with the first team from there (thanks Dm Elem!) but crashed in the last mission. And just to show how many attempts I've made at this, I've already leveled up to 19, and am 1/3 of the way to 20. Finally hand-picked a group today (1 Monk plus me as support heal, 2 Warriors, one Necro and one Elem), and got all the way through, killed all the priests, killed all the bosses and 3 of us were pummeling the very last mob when I had my third crash of the weekend (and yes, I'm investigating why that happens).
So I've done this upwards of 50 times... up to the last 5 seconds, where we win. It's enough to make you cry.
*Please* Any suggestions from folks who've done this mission?
