It is important for users with slow/restricted/limited internet connection to avoid unnecessary request to the server (e.g. request to submit a form containing invalid data, which will eventually get rejected by the server). The waiting time for the response may become a reason for a user to leave your web page, and then talk bad about your web site to friends and relatives, or even to whoever.
