This just works.
My group is usually WAR in LS gear with max merch AA healer, very fortunate that my wife allows me to include her Raid Rogue, then I can pretty much include any 116-120+ toon.
Sticking points for me -- NOT the script -- are a few times the initial warriors will aggro someone and kill them, then you have to make sure you have DPS enough to kill the piggies - if you can get the last one to 10-20% before the bacon dude comes, you should be OK. Finally, I have had a couple of runs where the hunters are either under the ground or down in the tunnel -- that has caused trouble.
After that, just make sure you have the Bando set with standard/stun -- I made some 'Entwinded Hammer' - TS smithing IIRC -- works like a charm.
Thanks for the work in putting this together!!
