Yes! You could train your range, prayer, strength, attack, hitpoints and defence to 99 if you did that! As long as you stay there for half a year. And, a dozen arrows per 3 minotaurs is NOTHING. There are MUCH better and quicker ways to get iron arrows than killing minotaurs for endless hours. And the law runes. 80 laws an hour is NOTHING. Plus, people who can actually kill the weird purple skeleton things in 1/2 a second without taking any damage would have to be at least lvl 70+. And, as stated by a couple of the players above, nobody cares about body runes or iron arrows.
