I was going to just going to autofighter it in f2p, untill I had half decent stats. then switch to p2p soulwars, much easier :P Still waiting for autofighter auth though ;) And How about this:
70 Attack
60 Strength
80 Defence
90 HP
84.75 CMB
Sounds good.
Try and see if you can squeeze another Attack/Def/HP level in there without going over 84 CB though?
