I'm here VMing you with various points:
Firstly...
I didn't get to read through the thread, so I dunno if this has already been said, but instead of setting behaviours to "Look Down", just use "No Movement". This was, the posession bug won't occur at all :) That's usually the problem.
Secondly, I'm going to approve your team thread, though I think you should combine the "Introduction" and "Why Should You Join?" sections, and flesh the combination up a bit. Otherwise the thread is quite decent.
So that's all :)
