Allow us to override and SET new target in fightclasses

Yes, please! 

Hello, not tested:

        wManager.Events.FightEvents.OnFightLoop += (unit, cancelable) => {
            var newTarget = new WoWUnit(0); // your code to found new mobs

            if (newTarget.IsValid && !newTarget.IsMyTarget)
            {
                Fight.StartFight(newTarget.Guid);
                cancelable.Cancel = true;
            }
        };

or

        wManager.Events.FightEvents.OnFightLoop += (unit, cancelable) => {
            var newTarget = new WoWUnit(0); // your code to found new mobs

            if (newTarget.IsValid)
            {
                if (!newTarget.IsMyTarget)
                    Interact.InteractGameObject(newTarget.GetBaseAddress);
                // your code here ....
                SpellManager.CastSpellByIdLUA(123);
            }
        };
