ok, i see what you mean. But i think it all really comes down to personal perspective in this case. I really had no problem with the waiting period myself, and more patience have a greater reward.
When i was on the 24hr meditation, I'd explore, buy more creatures, talk to people on line (when someone would actually talk that is) to find out how best to go about rituals and game/story related objectives, or I'd just log out and do something else for a while.
With the storyline, since it is such an important part of the game, I think the creators had in mind a deep and intelligent world that you can just breeze through if you want, but that does kind of take away from the game.
If you were to receive the same bonus rewards for "continue now" as you would with a 24hr meditation, or the 24hr meditation was completely removed altogether, I believe it would detract from the intent behind the game/story. After all, when you meditate upon a course of action, that means you are (supposedly) thinking hard on the subject to come up with the best response to the situation at hand. Hence the greater reward for deep contemplation. Why should you be rewarded as well for just "winging it"?
