Viritess, I completely agree. I'm all for the opposition of pointless time sinks, but I'm also for adding an element of "chance", so to say. Nothing like the claim wars of XI, but enough to make a player go "oh!" as they're traveling towards a certain objective, stop, and take advantage of a situation that may not always be available to them. Going back to the frog example, I liked how you brought up that the amount of rain is dependent on the area that you're in. If you're going around Uldah for a large amount of time, you'll rarely see the mud frogs spawn, but when you travel to Gridania, there's a decent chance it will start raining on the way and you'd think "Oh, hey! I should stop and farm some mud frogs while I'm here and try to get 5 or 6 skins". That's sort of what I envision when I talk about mechanics such as these.
