behind enemy skill radius?

This is my profile i have been using, however sometimes impulse drive will spam over and over at the rear and not use other skills. Do i have to change the radius some how?

Code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.InteropServices;
using System.Text;
using System.Windows.Forms;
using ff14bot;
using ff14bot.Enums;
using ff14bot.Managers;
using ff14bot.Navigation;
using ff14bot.Objects;
using TreeSharp;
using Action = TreeSharp.Action;

namespace Kupo.Rotations
{
    public class LancerDragoon : KupoRoutine
    {
        public override int PullRange
        {
            get { return 3; }
        }

        public override ClassJobType[] Class
        {
            get { return new ClassJobType[]{ClassJobType.Dragoon, ClassJobType.Lancer, };}
        }

        protected override Composite CreatePreCombatBuffs()
        {
            return SummonChocobo();
        }

        protected override Composite CreateRest()
        {
            return DefaultRestBehavior(r => Core.Player.CurrentTPPercent);
        }

        protected override Composite CreatePull()
        {
            return new PrioritySelector(
                r => Actionmanager.InSpellInRangeLOS("True Thrust", Core.Target),
                new Decorator(r => (r as SpellRangeCheck?) == SpellRangeCheck.ErrorNotInRange, new Action(r => Navigator.MoveTo(Core.Target.Location))),
                Cast("True Thrust", r => (r as SpellRangeCheck?) == SpellRangeCheck.Success || (r as SpellRangeCheck?) == SpellRangeCheck.ErrorNotInFront)
            );


        }

        protected override Composite CreateCombat()
        {
            return new PrioritySelector(
				Apply("Internal Release", r=> true, r => Core.Player),
				Apply("Bloodbath", r=> true, r => Core.Player),
				Apply("Blood for Blood", r=> true, r => Core.Player),
				Cast("Second Wind", r => Core.Player.CurrentHealthPercent < 80, r => Core.Player),
				Cast("Invigorate", r => Core.Player.CurrentTPPercent < 60, r => Core.Player),
                Cast("Full Thrust", r => Actionmanager.LastSpell.Name == "Vorpal Thrust"),
                Cast("Vorpal Thrust", r => Actionmanager.LastSpell.Name == "True Thrust"),
                Cast("True Thrust", r => Actionmanager.LastSpell.Name == "Phlebotomize"),
				Cast("Phlebotomize", r => Actionmanager.LastSpell.Name == "Disembowel"),
				Cast("Disembowel", r => Actionmanager.LastSpell.Name == "Impulse Drive"),
				Cast("Impulse Drive", r=> true)// r => Actionmanager.LastSpellId == 0 || Actionmanager.LastSpell.Name == "Full Thrust" )
                
                );
        }
    }
}
