That is often true. Players are players for a reason, and not game designers. So they sometimes want things that they don't know would actually be bad for the game and reduce enjoyment.

My strategy is to try and figure out what the desire is behind the request. What kind of experience are they seeking? Sometimes by looking at it that way I can make use of an idea even if the pure form isn't so hot.

Then there are times, of course, when players submit ideas that are straight up awesome. I love when that happens.

More common is when a player submits an idea that is similar to something we'd already been kicking around. When that happens, we take it as confirmation that it is a good idea since players and staff had the same idea.
