I think it's ok in situations when you know you have no chanse to survive. If i was in this situation and i had a satchel i'd definitely use it. If they wanna kill me, i'll make 'em pay for it and it also helps my team. But it shouldn't be used as an offensive tactic. Well i must admit i did it with other games, yelling KAMIKAZEE or FOR ALLAH!! while running at my target but in RO it would just be a really stupid move. It'd ruin the atmosphere and the general gameplay for my enemies so i just use common sense. In RO i always act like i would in real life.
