So normal drush FC turning into a Hoang is not dangerous at all, incase you decide to save villager time. It’s just too much considering Goth early game is strongest early game there is in the game currently. I hope you’ll see this sooner or later for yourself.
Sure it’s not straight forward, but the point is it’s stronger than standard, covering for the weak phase in the Mongols game plan, you realize Mongols always were one cut below strong castle age civs, now they are stronger than standard making them perfect all rounder civ with HEAVY early impact with the hunt bonus and scout timing. It seems to me you’re still failing to put together all the pieces on how well Mongols do in terms of feudal and castle and how strong this new option with the extra HP is for them. If it was standard steppe lancers, sure no problem as they are weaker than knights but the bonus is just too much.
