Need help for barb combat.cs

[asd3612808]

For the barb, when my barb see only one trash mob, he doesn't Leap, how can I fix that?
what do you need to change?

public static bool CanUseLeap
{
get
{
return
!UseOOCBuff &&
!Player.IsIncapacitated &&
CanCast(SNOPower.Barbarian_Leap) &&
(TargetUtil.ClusterExists(15f, 35f, V.I("Barbarian.Leap.TrashCount")) || CurrentTarget.IsBossOrEliteRareUnique);
}
}
