NOTE: there's been a cut in the first vid. I soloed this ini a lot on normal and heroic mode... and the heroic trashs have a far wider aggro range.
However the bosses seem heroic.
If requested I'll show you a video how to pull the endboss and also a way to come across all of the CC immune guards.
however if it's you performing on those vids I'll +rep you just for doing it

(the technique is not new ... not at all^^)
