metal bending is strong, but the way he uses it is quite weak, he only knows how to make a spear and hurl it at the opponent, can't he just crush or tighten the armor or the helmet the soldier is using and be done with it easy win, also he can used this technique of crushing the enemy from a lomg distance since he can see from afar and still can use his bending just like what he did when his fishing but instead of earth spike he should use metal bending and crushing the armor/helmet of the enemy and watch the enemies get confused or terrified from being crushed by their own armor, this can also be used on the tank/ship the fire nation is using
The MC needs to put some more emphasis on his Agility man...Usually the faster fighter is the one that will win...Anyways, with so much focus on Metal bending, i hope he will actually carry some metal on him at all times and even crush the fire soldiers by compressing their armors and helmets, otherwise it would be a waste of points...
