People don't talk about the waterparks probably because Water rides at the waterparks are not "unique" and would be similar as those in your local water parks. With the limited time people have, they would rather NOT spend time in the water park unless they have ridden all the rides in major 4 disney parks which are unique and one of the kind and have a better theme. Water parks tend to get busy in the afternoon so it is better to get there at rope drop. We got "waterpark or more" option for our upcoming trip. my plan is to spend half a day at a water park and only spend one evening at Epcot and probably visit the water park again after a morning at DHS or AK, and definitely waterpark again on my checkout day. .. I am so looking forward to visit the water park than anything else!
