MP Research strategy help

[Pirateiam]

Ok I have a few multiplayer games under my belt now and after a few learning games (getting my a## handed to me) I Have become comfortable with most of the games strategies. What I always seem to lack though in my games (even if winning them)is in research levels. I may control close to half of a map but I still seem to be behind in research. I purchase as many mages as seems appropriate and even equip them with research items but that still does not help. My instict is telling me everyone is using Skull Mentors in mass. Anyone wish to share thier (MP)Research strategies?

Thanks
