fastest way to get from lvl 30 to 50 on a fighter?

I figure i'll ask this here instead of making a new thread . just a simple question. If I take a 4x fighter/page with powergaurd and take him to kents with my dk. run the page/fighter into all the mobs and then kill the mobs with my dk, will the page/fighter get 40% of the exp?

or more simply, can I leech a fighter/page by just running him into mobs with pg whilst the party kills the mobs?
