I have lots of experience with Obby Maulers, long before 07scape came out. It was and is still my favorite build, I just no longer pk.
This is the rule I've stuck to with each obby mauler I've made. It should always be strength based, once it isn't , it's useless. imo.
There are all different kinds of mauler's and play styles, to say one is wrong or my opinion makes me inexperienced is just ignorant.
