Yea. Generally if you look at an f2p player they'll have a considerably high woodcutting level. (and for a better example. look at the high scores. you dont even get into the high scores until 66 wc)
It's just to get RuneScape balanced, if they change it they would f*ck up the economy.
Because almost all skills need logs to train, or get money. For example, for rangingyou need a bow and arows, Bw and Arrows are made of logs.
If you'll change Woodcutting,Range would also change. And if Ranging changes .... will change to.
Its a so on and so forth thing. When pking becomes hot the price of cosmic runes goes up. you may think "why cosmics... you cant pk with those." ACTUALLY! pkers use diamond addy bolts (e) which require cosmics to enchant. There are other items that are affected by things that seem totally remote to the reason. If you really look at it, you'll find some funky things.
