I would say the Auto warrior macro would work best, but I am not sure how effective it is at that level. It might need to be tweeked some I would think. But that way the Necro could hold agro and basicly have 2 pets stomping down the mob.
As far as the research, I think a macro may already exist for it, if not one could easly be made. It would be alot like the tradeskill macros. Only thing is for most research you need to have alot of farmed items to skill up with so you will need to have said items on you when you start the macro. Redbot, Siddin, Zedmex, or someone else on sight might be able to make those for you, at this time thats a bit to much for myself. I am still slowly reteaching myself codeing lol College was sooo long ago.
