Guide to Maple Story account safety

I don't know how hacking scripts operate, but I do know that common words are weak, lengthy convoluted combinations of letters, (such as "heitarlinobenaril" are stronger, letters with numbers is stronger than that, and fully randomized passwords with small and capital letters, numbers, and special characters are the best of all. If you create a Gmail account, you can type in passwords for the account and it'll approximate how strong they are. Even hotdog1 or hotdog+= is definitely stronger than hotdog, but a fully randomized password is still better than hotdog1. Ultimately, you'll type in your pass so many times that you'll remember it whatever it might be; having a complex password therefore seems more beneficial because whatever you choose, you'll end up remembering.

Well, in Gmail, I just go for length, because I really can't remember where I put special characters. One time, I changed my password in MS to something with a space in it and ended up having to reset it, because it wouldn't work.
For Gmail, my password is a 29 digit number with a letter in it hitting the maximum for a password. I suppose nobody can crack that, but should I change it to something with special characters?
