There is already a fix for the aggro, even aggro's the gm's now.

it is about the 4th post from the bottom, posted by Angie.
I am going to use it as mine probably tomorrow time willing. So far the only problem I can see with the release is the same one that has been around for a while. The loottemplates not existing. The Zul'gurub creatures mainly don't drop anything and errors show as loottemplate not found.
That is far less effort then some of the work I've put into other ones.
