Fletching - I can see a possibility, with restrictions set so that you can't make any members objects, or rune arrows. Construction - I can also see a possibility of this being F2P, with only the ability to make lower level furniture, thus enticing free players to go members for the useful things such as portals. Thieving/Agility - I put two of these skills together because they both have the same reasoning for me. I think the chance of these becoming F2P is very small, because even if F2P is given just the bare bones, there's not much to make them want to become members. Upgrading Current Free Skills - I believe the chance of this happening is small also, because the point of adding something to F2P is not to give the free players some new high level content or entertaining thing to do, but to entice the newer players into wanting to become members. Ultimately the question is, what will entice them more, giving them a taste of a skill and having them think, "If I become a member, I'll be able to train this skill easier/get more rewards from it!" Or by not adding anything to F2P and hoping that they make a leap of faith for skills and content which they have never tried and know very little to nothing about. Older players know that Fletching is profitable at higher levels because they have either become members and tried it, learning about what happens after level 70 or have spent their RS careers as non-members hearing about it. New players however don't have any time under their belt to have heard about it, so that only leaves them with the option of trying it, which as a free player isn't possible. So what's better? Spending a while not paying because you don't know yet that is fun and profitable, or getting a taste of it right away, and becoming a member because you know that the good parts of the skill are only available there.
