Under (Advanced) settings there's an option for whether or not to kill mobs between hotspots - that might help, along with reducing your "pull distance".
Same issue - and no, bob2k it still attacks stuff for me. For example, I'm herbing as a tauren druid, so I shouldn't be getting out of flight form and wrathing things to death when I could be at the next node already. I need to disable this somehow, and I can't figure it out :-/
