I started learning to pull this island with my 24 frog Paladin, just for fun. All of the mobs were blue or light blue. I did not have any buffs I couldn't cast myself, and was moderately twinked.
This was my strategy:
First, clear the one kerran in the small hut to the front and right of the JoJo hut; this is the pull spot for the area. Pull the kerran outside of this hut and to the right - solo pull always.
Then Lull the "guard" outside the hut which is furthest from the hut you're pulling to, and pull the closer one. Then pull the one you just lulled.
Entering the JoJo hut, if one kerran cons higher to you Lull it - otherwise Lull either - and pull JoJo. You will get one add. Pull JoJo and add to hut, KILL ADD FIRST. (I chain stunned to keep from casting.) Then kill Jojo.
Easy peasy.
