What to do?

I have 250+ Mil so money is no option really...

My Current Stats:
60 Attack, 85+ Strength, 60 def,
90+ range, 43 Prayer, and 80+ Magic.

What I was thinking was:
Superheating gold bars to 99 Smithing and Magic,
Then Getting 95+ Strength,
Getting Lunar Diplomacy Done, Venging and Dueling

So Should I Raise my Defense, or Keep it the same?​

 

99 str, 99 Mage, 99 Range 70 attack 70-75 def.

 

I see any Def higher then 70 being useless but why get 70 attack anyway?

 

Well then 70 def, you could keep 60 attack but that's gonna get boring after awhile.

 

Yeah I just figured I'd duel for a bit and stake haha, eventually I'll probaly just make it a main to be honest...
