Sounds fun, but it just seems like it wouldn't suit me. I like being able to go, "ooh, I need 1K Super Strengths/Attacks for my slayer needs", and being able to purchase them swiftly at the GE. There is no way I'm going to farm 1K (whatever herb) and then make 1K potions. Sure, it might work for F2P because all of the skills are basic, but in P2P, in order to do most members things (whether it be leveling efficiently, questing, or boss hunting) you will need to purchase most items unless you want to wait a day or more to do one quest. Yes, it sounds fun, but do I want to spend 2 days just so I can train some Strength? No. EDIT: May be fun for a level 3 skiller though. Mine the Ores, smelt 'em. Could be fun. Combat just adds too much of a hassle to kill efficiently.
