lol JAGUARDIAN, there's an easy way to kill it with temjin though hehe, i found out this way when i was in standard 6 or something haha
ok, here's how to do that, when you're facing JAGUARDIAN, using temjin of course, 1st try to evade his spread bazookas and lasers, then after those combo attacks, he usually will pause for a while, or just plain moving around doing nothing, here's your chance, with temjin, just stand and throw the bomb to the ground, and NOT TO HIM, because if you throw it at him he'll evade then he'll shoot, then you're dead, be sure to stay at a distance and make sure the blast of the bomb is no where close to him BUT infront of him and blocking his view.Now the magic begins, Your bomb will deflect his bazooka shells and if im not wrong, the bomb blast will deflect his lasers too, and at this time, he'll just stand there doing nothing and he cant see you(though he's an AI) because the bomb blast is blocking his view, this time, stand on ground not moving, just use your rifle and shoot and shoot and shoot.
eventually, he'll fall down in a few shots. After that, while the bomb blast is fading away, your bomb might have been charged enough for the 2nd time, same goes for the 3rd, the 4th, time things nicely and you'll win an easy battle

I've never seen a pro balbados player though, but i just read online that it is a very very deadly machine when in the hands of a pro, really, no kidding.
