Do you even make your sims swim? All they can do is swim laps and splash people. There's the jumping platform but that's just a way to get into the pool. I like building pools but they're so borin...
Yes, being unhappy with some aspects of TS4, and expressing that unhappiness, does not mean simmers have a "need to try and find ways to diss" TS4.
I fear our frustrations with understanding each other's viewpoints are leading towards making incorrect statements about each other's motivations, and we don't really want to go that route, eh?
ETA: Must be pretty wearying trying to explain the game engine to those of us who don't know much about it, I imagine! :)
