You'ld drop the teleport, sacrificing some mobility ...
Move the Explosive Blast to right-click, and in it's place on #3 you'ld put Force Weapon with Blood Magic (giving you some lifesteal) ...
the +10% damage from Force Weapon will put you up over 200k, you'ld have a little more survivability with the life steal, and just sacrifice some mobility by losing teleport.
