Why would Jagex waste their time with F2P people...they're busy enough running runescape and giving PAYING players new benefits. F2P is fun but really guys...subscribe to members.
None of those are going to come out unless its the Dragon Pikaxe, all the other ideas are rubbish. Because they would be godly expensive and only dropped from a level 8347 monster that you could only fight solo and uses melee, magic, and range in one attack. -_- like I said, its never going to happen.
The only thing this update is useful for is the grappling hook to get to the water obelisk faster. Which isn't very good assuming that everyone can make air orbs.
