In my opinion, only Jagex can decide whether ideas (as cool as they are) like these would fit into the game without massive repercussions such as drastic price fluctuations, the compromising of aspects of the game (e.g PKing, training, etc.). Only Jagex has the statistical knowledge of the game to know if this would work. For now, these are just cool ideas. On a less serious note, I like them ^_^. But in my opinion a piece of equipment always is better than for example, your whale idea. Just my two cents. @ The Magic idea: How about you can switch magic books on a 30 minute cooldown.
