This is ONLY for WoWUnit and WoWPlayer, not ANY other type of WoWObject.
@Droidz can you please fix WoWUnit.GetDistance.GetMethod? It needs to be this.Position.DistanceTo(ObjectManager.Me.Position) - this.CombatReach - ObjectManager.Me.CombatReach. ONLY on WoWUnit. I've tried creating a runtime patch for this, but unfortunately you cannot patch properties at runtime
