Runescape what is the most important combat skill?

If you could have 99 mage, 99 range, or 99 att and str i would say if you have lots of money mage because u can ice and blood barrage. if you have moderate money like 3-5m then range using like d bow and rune arrows but if u are poor with 1-2m be a warrior with like 1 def pures are the best and u could buy a d scim whip dds berserker ring and a glory ammy thanks
