Dictionaries method actually is most useless method. Even a good dictionaries take month to crack simple password

Dictionary attacks are actually one of the fastest attacks you can perform, although not guaranteed to be a success it's a hell of a lot faster than a bruteforce attack which can be measured in lifetimes (of the universe).

I wouldn't call it useless as most people don't really understand the risks of having a weak password. There's also the combination attack which is based off a dictionary attack that can greatly increase your chances of recovering the password if you have a decent dictionary.

If you don't know enough about a subject to form a valid argument don't post.
