I think that, if you have time of course, you should try and update the leveling system with woodcutting and fishing. With the Wc/Fishing i think that the amount of wood/fish or the speed that you get it at should go up with every 10 levels you advance in that skill.
Say you reach level 10, The amount you cut at once would move up from 1 or 2 to 2 or 3 logs per swing. Or another thing you could do when they advance 10 levels is create a new item (wood level 2 / Fish level 2) and the wood/fish level would go up every time they advance that 10 levels.
I hope you don't overlook this, please get back to me when you can.
Thanks.
