I think you are right ^^ If I want to improve my Korean, it is better not to use Romanization. I totally agree with you. I won't use it again. Thanks for your comment and your advice. :)

better not use Romanization.. it's easier and worth to put efforts just to learn 한글, practice reading it and use text-to-speech online to hear Korean word written in 한글 should sound.. and of course, it's totally worth learning rules of reading, like 신라 [실라], 굳이 [구지], etc.
