I think the treasure deck of Ravenloft includes many mediocre cards simply because it's expected that you will be killing a fair few monsters in any given game with each one of them yielding a treasure. You'll probably be picking up between 8-12 treasures per game.But, if you hate those cards so much, take them out and then play a game! In fact, playtest it a couple of times! Then come back and tell us how it all went. Tell us whether it made the game more fun, easier, etc.
If you have Ashardalon, you could try mixing that treasure deck in with Ravenloft. Ashardalon has a greater number of powerful treasures. I don't necessarily recommend it though, unless you're creating your own adventures where it might be relevant.
