9th, make Ruby Bolts (e) in the ranging shop. (Or the credit shop, but that'd be weird) They're the best for bosses. (:
10th, speed up how many logs you chop. I chop a regular tree for like 2 minutes to get 1 log.
11th, Slow down Firemaking. It is WAY too fast. I got like 67 Firemaking with 1 regular log. Everyone will have 99 fming this way... :s
12th, make a bank at all skilling places plawks. It would annoy me much less.

13th, speed up fishing a little. You don't catch fish very fast...
15th, give me better slayer tasks! I'm 99 slayer with 137 cb and I get Chaos Dwarfs and st00f.
Btw, don't lock this thread because I will probably add on to it every time I think of something. :3
