If you're going to get defence, do it right. There isn't any point in 20 Defence it hardly helps at all.
I say stay 1 Defence, 60 attack, and 44 Prayer, considering the fact you can't smite peoples stuff anymore, it's all on chance.
If you afk'd at Soul Wars say once a week, and used it on HP, you could have 99 hp cape at a low combat level. 60 attack, 99 strength, 99 range, 99 mage, 99 hp, 52 prayer, is level 83 I belive. I would say get that for long run goals, and skill from there on. I only say this because I wanted my account like that ):
EDIT: I also have a 123 main, which I find quite fun. Mains are fun to, in my opinion more fun. I say just get good stats as a pure, that way training Defence won't be such a bitch
