I need help with pulling in RFC

When I finally clear most trash and there is a bridge over to the bosses island, there is a void walker on the other side with about 5 other lv 15 elites.

I cannot managed to just pull one or two of the mobs. Rather the the island of 5-6 elites chases me down and kills my 5 box team.

My team is now: lv 15 Pally + 4 lv 14 Shammy

How do you pull those mobs? Or how to you kill them all if you cannot pull just one?
