Getting to lv60 strength takes less time than the 75/80/90 attack therefore you are able to OSRS gold begin making more PKs, and mauls are extremely cheap to replace in the event of the day of death. Pures of Strength have access to the formidable Berserk ability, but will have to spend an attack level for the ability to utilize some of the more useful attack capabilities in EOC, and completely lack a special attacks in Legacy.
Defence levels can be completely not considered in Legacy, but in eoc the Freedom ability is crucial. Keep your mage/range at 50% or less of sum of your attack+strength.
Leaf is a great point, and if dual Ascensions are better than Nox and worth roughly the same amount of money, there's really no reason not to buy these instead.
In the event that you do not plan to create warbands using the Nox in the future, but that's basically inviting disaster to happen. Sorry for the inconvenience, but far more experienced PvPs are losing their bows and similar weapons due to mishaps (forgetting how to charge Prayer, dropping it while stunned , for instance) or because of killing users. Not to mention you'll get blocked hardcore by waves of welfarers hoping to triple their bank which will increase the chances of you losing it, making warbands a total chore.
Prior to the weekend before the bxp was announced Nox Bow was fairly solid, with a value of 320M. Then, after the announcement, it began dropping a few times and was able to fall to rs gold 2007 as low as 220M (if I'm not mistaken). Then it went back up to 300-320Mish.
