yes you should get your range level up, because if your f2p, which im taking it you are since the 41 attack, could be wrong, but you could use range/2h combo
i'd have to agree with everyone else, with getting your range level up, because once i hit 70 strength, i shall be getting 70 range. It is always a good skill to have and can help when in tight spots, I.E if your staking and he has you, you can run and stun and range
