How about adding a rapeprot for all the "pieces" as well? So when someone
kills the mob, he can't obtain (at least some) of the parts/pieces/keys
whatever needed to kill the mob. That is, they could not manipulate the pieces
in question in any way. That way, there would be no point in running through
areas just to impede someone else.
Then again, this might require some countermeasures, since if some suffeli eq
becomes too commonplace, they might be tuned.
Just my two cents.
