I dont read any manga except Dragon Ball.
That's the first time I heard a fan who only reads one particular series. You're not getting much enjoyment with one series. When you're in Anime Vice, you'll definitely pick up and read some new stuff. Plus, you're active in the battle forum, so you do need to know other franchises out there unless you're only dealing with pure DBZ battle threads with only DBZ combatants. Though, that won't give you the full experience in the battle forums.
You're free to do what you like. I'm sharing my suggestion. Eventually, you will get bored of one show or manga.
